Something like mathoverflow in other sciences Are the sites similar to mathoverflow in other sciences related to mathematics? statistics, computer science, physics, economics, etc?
Let me explain what I mean by "similar": those are sites devoted to posing questions and answers,in these areas. I do not insist on the precise format of "mathoverflow" (reputation points, badges, etc.). But I am looking for general multi-participants forums like this one, so scientific blogs do not qualify.
 A: Well, MathOverflow is based on Stack Overflow, which is about programming -- though not, perhaps, computer science in an academic sense.  Good question, though!
My guess is that such sites would tend to degenerate quite quickly unless the subject lends itself to questions which can be answered.  Such questions tend to be predominantly mathematical, perhaps by definition, so perhaps they could be incorporated into MathOverflow.  Already we are seeing an increasing number of questions on mathematical physics.
A: Here is a brief list of science-related sites that run on the same platform as Math Overflow:


*

*Science


*

*Science Stack

*asksci.com


*Physics


*

*physics.stackexchange.com

*PhysicsOverflow


*Electronics


*

*Electronics Exchange


*Programming


*

*Stack Overflow
A complete list of these sites is available here.
The one thing that I personally feel is missing is a lower-level mathematics site (a Math Underflow, if you will).  I understand the desire to keep Math Overflow relevant and interesting for professional mathematicians, but there is currently no equivalent site for amateurs and students.
Update: (Sept 2010)A math site for university level mathematics exists now.
There are also sites for theoretical computer science and for statistics.
(April 2011) There is a TEX Q/A site!
(September 2011) Area 51: science contains new proposed stackexchange sites related to science. We can mention especially proposals for Theoretical physics (and mathematical physics) (closed), economics (closed), research economics, game theory, computational sciences, philosophy (the site is running), numerical models and simulations, Mathematica, mathematics in german.
