Subject Re: [VOTE] Accept Cassandra into the Incubator
Date Sat, 27 Dec 2008 19:26:59 GMT
I'd like to see some plan on dealing with the fork/community stuff. We
*know* it is a problem, and I'd like to see how this is being
addressed in the proposal. In my opinion that is the crux to this
proposal. Just going Apache is not going to solve problems. The
feather is not a magic wand you can wave around and make problems
disappear.

What will happen when the original coders won't come with the project?
What when they do and then disappear *again*? How will you get the
folks on board that don't want to come over?
