Stack Overflow is a very important site when it comes to finding information regarding the technical details of certain software products. For questions such as "How do you integrate this?" or "How do you modify that?", you can usually find the information here, directly from people who already faced this problem and solved it.
One of the key factors of success for any kind of software is how easily adaptable it is to the different circumstances of the people who will use it. So, having the answers to those questions in a single place, with the information properly compiled and edited, and a powerful community system to avoid wasting time on useless information is very very important.
I have seen countless software projects fail because of poor documentation that is hardly updated, badly organized, or just covers basic usage and no advanced technical needs.
So my question is this: Is it possible for businesses to create accounts and to answer questions regarding their own products? And is this kind of usage of the site supported by the community vision?
I think business could use this as a HUGE opportunity to grow their documentation (by learning from the questions themselves), improve the user experience and give more credibility to the capabilities of their products. And I think this applies both if your company sells software, or fitness equipment (on the fitness Q/A site)
This could also mean an additional business idea for Stack Overflow, offering its services to companies in order to have "verified profiles" or extra information, but the point of my question is just about the possibility of business accounts and how this fits with the community vision of Stack overflow, and the Terms of Service.
EDIT: I changed the question title to better match what I intend to ask
Just a little bit more information to support my question:
1) Before asking this I made a search on the Stack Overflow user database for corporate accounts on Microsoft, Google, Apple and a few other large companies. Found people who used the words on their nicknames but no corporate accounts appeared.
2) I read the entire FAQ for information on this matter, nothing appears regarding corporate usage other than advertising information, but nothing about making questions or answers with a corporate identity.
3) I also made a google search just in case, but didn't find anything on this matter.
