I think labmeeting is a great idea and also something which could be very useful.
Specifically, I believe there is a lot of value in breaking up the traditional research publication methods - Conferences, Papers, Journals and the costly (atleast for developing nations) access to this material controlled by a view publishing houses.
Research and collaboration needs to open up for everyone and should work freely over the internet rather centered around conferences etc. If labmeeting can enable something like that (which I guess is something its founders would have though about) it can very well change the way research is conducted.
We use Ruby on Rails. I prefer Django but learning Rails was trivial after having practiced with Django for the past 2 years. We use Python for a number of tools internally. Lucene for indexing, Lighttpd webserver, MySQL db. Standard stuff.
I have a Ph.D. in physics ('05), and this looks to me like something that would have been really valuable during grad school. Unfortunately, I can't try it out because they insist on a current academic email address for registration.
How did you make the transition from Physics to Hacking? I just finished my Physics PhD (along with a MS in CS) and have been pondering this move for a while... any suggestions would be greatly appreciated.
I think scientists need a social network more than anyone...not so much a completely social network but definitely a professionally focused social network like this one.
There are also some other "professional networks for scientists" out there. Some friends of mine have started epernicus.com, and I've seen some others, too.
I do not think the idea is pointless. I want something like this. I have a ton of academic papers in pdf format that I find hard to manage. It's the webmynd style augmented memory type of functionality that I would find most valuable.
