I wonder how many companies have considered selecting GitHub as the place for their source code, wikis, process, issue tracking, etc but hesitated or went with another vendor simply because the financial future of GitHub was an open question. Now, with Microsoft making that question a moot point, I think a lot of companies will now make the move to GitHub knowing it will not go away.

Ironically... having Microsoft behind GitHub and being willing to lose money on the company forever could actually be the reasons it has a hope to turn a profit some day.
