I must confess that I "learnt" SEO by undertaking in black hat stuff. I used various programs to mass post spun articles to blogs and directories and anywhere else the software let me. I spend hours and hours on crafting generic piles of #### to post everywhere I could.
I became so good at SEO for about 2 months. Things were looking good.. then penguin hit.
Not to let that stop me, I spent even longer crafting the perfect anchor text densities, private blog networks and anything else I could to try and fool Google.... 1 month of semi-greatness.
Ok, starting to learn alot of great things. Learnt about penalties, and more of what Google wanted. Let's try white hat.
With white hat it was all about the content. To my surprise I spent less time working, more time on producing a better site, and to my amazement ranking higher than I ever did before. That is not to say I have never had issues with content quality (short news posts), but I have never looked back since focusing on content and forgetting about links (although some content I have written is especially to attract natural links from other blogs).
Anyway, just make sure you don't mind losing any site you try black hat stuff on, but still recommend white hat stuff all the way.
