None of them although close.

You don't have to take my opinion seriously. I could work in Tescos and be splurging false information out on the Internet. I could be an elaborate hoax!

However, please don't write off people as "just some enterprise business that isn't exactly known for its technical competence" because we all know that startups get it right all the time as well...

As for do I know versus do I think, there is the third option do others know and that is all that is important when it comes to getting paid...
