Science and Technology Forums
This is a big suggestion, so I hope the criticisms will be as strong as possible—adding a forum is not something that I think should be done unless it’s going to have wide support and usage, or at least some important application for the site.
I’ll frame the idea: create a space where members can discuss science, experiments, scientific thinking, contemporary scientific issues, and technical material. Perhaps computer science and psychology should be included in discussion along with physics, chemistry, biology, and the wide range of related fields and subfields that may be of interest.
And I’ll frame the motivation behind my idea: to promote science as a field of knowledge that pushes forward and refines everyday thinking. Science can and should be fun. A forum like this would not just appeal to specialists—it would inform and encourage enthusiasm among amateurs and science phobes alike. Science encourages us to explore the world and challenge ourselves to rethink the ordinary. We have a political and religious discussion forum—a Science & Technology forum would be a nice companion forum for developing community, learning and interest.
+ Later on something like this could be a great way to introduce younger members to an interactive environment for fun and learning.
C'mon, we're all nerds anyway!

[Edit: I have no idea why I was striking out where I wanted to put bold text.]
yes from me too^^ nice idea and could be really interesting to discuss with equals but physics.. all the stuff there is eg the sun(and big blue's) is imo very interesting..
when there are enough ppl who would use this forum(and use does not mean spam etc +1's etc) then it would be great.. but the one who leads it should take care to keep the spam out of there^^
