Note that it's not 5 free private repos, but 5 private users. You can have unlimited private repos. So, in a small team you'd probably never have to pay. I wonder what has led them to this decision business-wise. Was the competition from github so overwhelming that they decided to counter it with with relatively drastic measures (giving up lots of $$$)?
ah yeah, I may be wrong, but I swear it started as 5 repos, then they changed it to users.
Anyway, for some reason one of my free accounts has unlimited users right now. Not sure how that happened but I think it might be because I had more than 5 users on a repo before they made the upgrade? Pretty awesome regardless.
