I can now safely say I am hooked to alltop. I wasn't so sure at first. Too many topics/categories seemed repetitive; "Opera" turned out to be a collection of blogs about the browser; that orange banner was a pain in the rear. But all that was four weeks ago. Now I find myself checking out news and blog updates regularly on alltop rather than via RSS. And I've made peace with the orange banner.
Searching for blogs by topic is just not easy. Google's own tool has been gamed to death by spam-blogs. (Simply enter an alltop topic into Google's blog-search and compare the results with alltop's blogs). Alltop is filling an important gap in the market while destroying my productivity. What could be better than that?
