you're correct. most of the sites listed in this thread are niches, not micro niches. 50 year old guys is a niche. 50 year old guys with shaved heads is a micro niche.

btw, do i get to review boykakke?

That's my understanding of it anyway. I do think it's a trend, surfers want more specialized and unique content and the webmaster community is starting to catch on and deliver to these surfer's desires.
