The socially powered search engine, Sproose definitely does look promising as was said on the page where I found it, over at Swollen Pickles.
I've added it to Chexed.com, so now you can vote on pages if you like them, and comment on them at Sproose if you feel like signing up there.
When you vote for pages, it will help other people find them easier. Also, if you create an account, you can keep track of your votes, similar to "diggs."
So go Sproose things up!
Edit: I have just found out, votes are only temporary unless you sign up! So I signed up and I'm voting now... You can see my sproose profile now. Yes, as a president votes for herself, I vote for myself too, except here, I can vote for friends, competitors, and random people too! It's pretty sweEeet!
