In February 2007, Git 1.5 was released, finally making Git more usable for normal people.

Despite Git’s popularity in the Ruby community, the only Git hosting service available at the time was Petr Baudis’s repo.

Another issue for Git core developers was that Tom, without any discussion, forked and customized the Git daemon using Erlang to meet GitHub’s own needs.

Some expressed dissatisfaction that GitHub was making money off Git while core Git developers didn’t see a share.
