I have been playing around with Scour today, and it's pretty interesting. Scour is a very powerful search aggregation engine, in that it will search for terms, images, or video across the top 3 search engines and weights your results according to Scour's own algorithms. What? You know of other search engines that combine results from multiple sites?

Let me tell you why Scour is different. When you search, you're given the chance to sign up as a member. If you choose to do so, you become an advisor to Scour, which means:

You can review and provide feedback (by voting) on the quality and relevance of the searches you received. Scour then folds this feedback into the mix for future searches to make them better.

You can earn points for ever search, comment, or vote you contribute to the site.

You can invite others to join, and get points for the stuff they do on the site, as well.

You can redeem your points for Visa gift cards.

It seems pretty cool so far, and it's free. One nice thing: if you're busy and just want to use it as a search engine, there is no pressure to do more than that. And you still earn a minimum of 1 point per search.

Sound interesting? Click here to sign up for Scour and start earning points for searching (if you use this link, I'll get some points for what you do). And once you're signed up, you can invite other people and get points for their activities.
