We built Theneeds with a similar idea in mind, that people should come and just find interesting stuff, personalized according to their interests (we learn from users' activity to get smarter about what the interests really are).
We focus on a broader range of topics than just tech & science, thought there is a good selection about that too.
I tried your site out, it's pretty cool but some of the backgrounds make it completely unusable. Make it as minimal as possible, people are meant to stare at this for a long time.
The background can be turned off, but we actually decided to keep it on by default. We think that it creates a more "full-immersion" experience and helps not going OT (out of need actually ;). We don't have numbers to support this, but... that's the idea!
