"HOWEVER...I'd also buy the keyword.com/net/org domain if it's available and I'd probably create a blog on there that will eventually link to your main site. Doing this will get you some additional traffic but also prevent a potential competitor from grabbing an EMD and outranking you in the short term. "
Phil I wanted to clarify something with you. I have added the link below from search engine land talking about exact match domain penalties I believe you will agree with me that you want to focus on one domain and one domain alone it's all right to 301 redirect your other brand ( Meaning identical domain to your brand name but with .net .org) domains to the same domain that will be your brand/regular domain.
You and I both know exact match domains still work but honestly if you look at the trend there dying any new exact match domain will get nothing because Google will index it for the 1st time and when the algorithm has to make a decision on if firewood.com will rank for firewood I bet it will. However one day very soon it's going to drop. And 100% of that content that could've been put on the original domain with the new brand name associated to it will be unavailable as you do not want to take the content that has been indexed on a different site that was possibly penalized and Google knows was linking to your site and put it on your website.
I would say the smart thing to do would be put the content on the site you want to rank do not create what Google will call a link network by buying exact match domains and having them link to you is violating googles rules now I'm not saying you're going to get caught, but my money would be on Google.
It's a $40 billion a year in revenue company if anyone thinks that they can beat them at their own game now that they're stepping up this increased anti-spam anti-manipulation effort I have had to take on clients that literally have not done things that I would've considered all that bad and Google has penalized them they are now having to spend quite a bit of money with no assurances that they will ever be listed at their former rank Ever again.
today you have to earn your place I would not ever create a blog on an exact match domain that I own because even if you private the Whois, and even if you don't run on the same server there is authorship and you're not going to get a domain to rank without authorship of a blog. Yes you could make up a name but he would have to make up a Google + account and build authority for that exact match domain to have it be worth anything. I understand that you might get a couple people linking to because they clicked on that and then you might have a giant banner saying click here and it would have to link to the real site.
My opinion is if you find exact match domains feel free to purchase. However do not ever use them just take them off the market if you feel that their threat to you. However I can assure you that they're not know the long run.
now if you are just saying buy .net, .org & .co I am 100% with you should do that for the brand domain you choose as your company name.
The only reason I recommend .co is I was too dumb to buy myself and had some guy tried to sell it to me for 4 grand after I bought my domain through an auction.
I want to let you know that there are many ways of getting the domain you want even if the registrar shows it's not available however you want to check it out and make sure there's no bad links pointing to it.
Here is a little bit about how exact match domain works that Google and the penalties put on people only from time to time that's why we see some people get away with exact match domains and others not.
Another reason I would focus on building strong content on one site do not waste your time with other sites and please remember this if you purchase your domains and their .net .org etc. from a registrar that allows you to "forward" the domain to the new site.
At a cost of up to $75 a year depending on the registrar I know quite a few do it. The bad part is even with that they Do not do that most of the time it is a simple link not a 301 redirect you want to be sure that you're using a 301 redirect.
I would simply use something that you know you can control all your domains from and has a tier 1 provider sending your queries out. it sounds crazy to pay for DNS but this is saving money if you use the less expensive options I'm listing below.
The best way to do that is used a quality hosted Anycast DNS service you can use DynECT my favorite, but expensive 10 domains costs $30 a month.
Or use a much less expensive service.
DNS made easy excellent extremely fast, and you get 10 domains for only $25 a year
There are two free options one is hurricane electric the others cloudflare both are better than standard DNS by quite a bit hurricane electric is more techie cloudflare is very simple I put more DNS information at the bottom if you care to read it
I would use DNSmadeeasy.com if you don't use Dyn.com as they give you customer support and are truly very high quality.

**Last week, Google announced the EMD Update, a new filter that tries to ensure that low-quality sites don’t rise high in Google’s search results simply because they have search terms in their domain names. Similar to other filters like Panda, Google says EMD will be updated on a periodic basis. Those hit by it may escape the next EMD update, while others not hit this time could get caught up in the future. **
EMD is more likely hitting domains like online-computer-training-schools.com, which is a made-up example but hopefully gets the point across. It’s a fairly generic name with lots of keywords in it but no real brand recognition.
Domains like this are often purchased by someone hoping that just having all the words they want to be found for (“online computer training schools”) will help them rank well. It’s true that there’s a small degree of boost to sites for having search terms in their domains with Google, in general. A very small degree.
But such sites also often lacked any really quality content. They were purchased or created in hopes of an easy win, and there’s often no real investment in building them up with decent information or into an actual destination, a site that people would go to directly, not a site they’d just happen upon through a search result.
Some of them lack content at all (are “parked”) or have content that’s taken from other sites (“scraped”). Google already went after parked domains last December (and made a mistake in classifying some sites as parked in April). It’s already been going after scrapers with Panda and other efforts.
Extended DNS information if you care
or use cloudflare.com rather not I would turn on the orange cloud would depend on what hosting company I was using and what site architecture was building my site with. Regardless you can use cloudflare's and Anycast DNS with unlimited domains for no cost. When you turn off the orange clouds next to the a records and came records it is just a very fast DNS system.
Sorry for the extremely long-winded response.
I'm sure you meant brand domains point those that your new one not to buy an exact match and create content on it.
I hope this is of help,
