Agreed. They are a shining example of what I look for in a commercial company building an open source product. Self-hosted, community edition with no fundamental deficiencies, hackable, and a CEO with more 3rd party presence (he's always on here in the comments) than anyone could ever ask for.
I only wish it were written in something which compiles native, like C or Go. Not bad enough to switch to anything else however, and it's really just my own personal dislike for Rails/Ruby.
Love the Gitlab-CI integration too, and am excited to see how it grows/improves over time.
