I think its a good thing, it can help people find your business and if you have reviews attached on google+ they can see that within your maps acct.

I would keep them, i even still use them with sites I'm building now because even though one search engine says they don't use them maybe another will and who knows if and when they will be important again. In my opinion no harm no foul. I leave mine.

Do you have the word homeless anywhere on your site? or even home?

Hey,

I struggle with adding content too, to me graphic on a web page look better than words, I try to add intriguing content and usually keep my wording to 400 words or more. Please seem to like looking at pictures rather than reading so maybe filter in some pictures or graphics within the copy.

I have 2 websites as well and they are in the same niche, i made sure the write completely different content that is helpful to my visitors. Different titles and descriptions as well.
