Say a company (or a team of contributors to a FOSS project, or whatever other group of people) wants to show off its expertise in some area. Would it be ok for it to create a profile on SO and let the people in the group use the account to answer questions?
It's ultimately up to Jeff and wouldn't be easy to enforce, but this feels contrary to what Stack Overflow is about, from using the rep earned to establish trust in the contributors to using it as a way to build personal brands. For example, if a major contributor on your team leaves for greener pastures, does your team still deserve that score?
If you want to show off your team's skills, build a nice gravatar to share, use your team as part of your display name, and link to your team-mates in your profiles.
I could see them going another level with Careers, allowing employers to indicate Stack Overflow users that already work there. After a few users verify the relationship, the employers careers page could show total and average rep.
Interesting idea. I'm going to guess (along with Pekka) that the official line will be no.
However, there is a specific use case that this helps with. If you have a team of members with their own individual accounts, and all are on the same project, it stands to reason that they will naturally end up upvoting each other -- not out of malice or attempting to game the system, but purely because they're already on the same page, and will likely naturally tend to agree with one another's posts.
In that scenario, sometimes the accounts end up looking like sock puppets, even if they're not. As a result, mod action may get taken. So while I think that on the whole the idea is probably not going to be well-received, I can see it potentially alleviating that specific issue.
Of course, that assumes that this issue is actually widespread. My hunch is it's not, and that the downsides of doing this far, far outweigh this one positive.
