GPL 2 for now

Last week I had a poll on Blazing Games about switching from GPL 2+ to GPL 3+ for licensing my Open Source releases. The voting breakdown was 57% for sticking with GPL version 2, 29% for going with version 3, 14% not sure about what this GPL thing I keep talking about is, and the remainder saying I should switch to a GPL 2 only license. I am thinking about posting a series of entries about my thoughts on the open source movement. I will make up my mind over the weekend, so don't be surprised if next week I start a series of rants about open source.
