THERE are two types of attitudes towards Microsoft which help the GitHub 'monopoly'; one sort of insinuates that Microsoft poses no real threat to Free software and the other says that despite this threat there's "no choice" but to embrace GitHub because "everyone is on there" (network effect).

GitHub does things that are quite bad for free software and is not interested in changing them. If you want to move off Savannah, please pick some other place.
The reason that attending to user requests for Savannah is slow is that there are not enough volunteers doing it. Would someone like to volunteer to help run Savannah? Can you find someone else who would like to do this?
