I have to be honest, I haven't even heard about it until I saw that it has its own (empty) category on this forum. Given that I never tried it before, I decided now's the time. I went to its site and here are my impressions after a few searches: 1. It's SLOW. It might be my computer, but it takes about 2 seconds to find search results, whereas even Bing takes less than one second. 2. It has a really weird design to it, but truth be told, it's pretty handy. The search results are all organised by categories, and you can expand the category you want. This is a feature I wouldn't mind if Google or Microsoft added to their engines. 3. The homepage feels...blank. I don't really know why, but even compared to Google, it feels blank. Overall, if they improve the speed, I think I would start using it. Now, I would like to hear your opinions on Blekko.
