I think this would be GREAT!!!
I was going to ask for it and actually REQUEST it even.
I'll tell you why... but first I also want to agree with Kevin & Brad. If people think this shouls NOT be implemented they should answer NO + explaination.
So... the why:
Contrary to TheTXI I believe (and know as a fact) that dev teams individuals post each numerous amount of questions in SO. And that to keep track of it, the team members send the links thorugh email, or Skype or chat or Twitter or whatever...
To have to inform manually to your team about the questions you have it's a pain. I see SO as a place to rise your Questions to both the community and your team members. And although I do have obviously the interest in helping out the community I have a even bigger interest in solving the Questions of my team members. And somedays I just ignore reading the list of the tags I follow. But I always read when my teammates post some question out there and I would answer it if I can.
Another point is: I don't always ask all the questions in Stack cause I prefer asking quickly to my team colleagues. But I don't like to go around interrupting people. We have a task management system and we modified it to ask questions between each other... and if NOBODY has an answer we would go out to StackO.
Would it not be GREAT if we could just post the questions directly in SO ?
The Community would profit from the questions and responses that we usually don't ask until nobody knows... and we could have more input than just the internal.
What about companies that have teams in different locations!? Why should teams look for internal solutions for the Q/A flow with an eventual resolution of "post in StackOverflow" when it can be ALL from zero in SO?
And regarding the concern of @TheTXI about teams up-voting team members and down-voting competition members.... COME ON!!! That is already happening out there my friend!
There is already competition among individuals out there, and teams or clans... In my team, we actually paste the correct answers even if we found it on the ofice out of the computer discussing on the whiteboard, while the community did't find anything. And we do it just to get the points to the worthy developer that solved it on the whiteboard, of course, then the rest of the team members that were interested and/or discussing vote up the colleague's answer.
You have to trust the community, it's not as if we are going to buy a yacht with our reputation points! (Can we?)
Most of the times, different answers are posted from people of our own office!
Yes, we actually have kind of an internal competition. ;)
So I believe that TEAMS would be great for the site, for the community and would fulfill a NEED that the developer teams have out there.
