I partly agree, but those that have done the research or already use Gitlab know that Gitlab's uptime has been problematic compared to Github's, which is a bigger issue for most companies than the community. As sytse correctly notes below, it's a lot better than it was a few months ago - but the pessimistic/risk-averse way to say that is "as recently as two months ago they were having major uptime issues". I have high hopes for Gitlab and I think they're doing great things, it's always great to see new competition in the space. And I applaud their transparency, it's refreshing! But it'll require some more "burn in" time before I consider it a reliable Github replacement, all questions of critical mass aside.
