In theory, this is great, but it's really hard to do actual work while wading through 6 separate reports of "It says the db can't connect to this host and port, what do? Derp!" The mailing list is even worse.
It's really hard to separate real, actual issues from a few hundred people who don't know how to run a ruby-based website.
Even the people that seem to know enough to help fix bugs are stuck arguing about whitespace and license choice. That's a waste of time both for them and the diaspora time when there are clearly bigger issues to solve.
