Thanks for posting this. I think a lot of webmasters (myself included) tend to make things too complicated for themselves. Like,
"I can't start a blog until I've researched all the possible keyword phrases I want to target and studied the backlinks of all my competitors." The main thing I took from this is just do it already!
Also encouraging - seeing how varied your list of niches is. I'm guessing you're not super interested in all of them on a personal level.

I'm sure it would help if I were passionate about, say, ebony tranny feet for example, but at the end of the day it all comes down to just doing the work.
One question...
Since your images load on their own page without any HTML or banners, I'm wondering what your Google image search results are like. Does the "original format" link go back to the main post? Or the big jpg link?
Thanks!
