Can you comment on the startup scene/general market for developers there? I grew up in West Palm and would like to try living there again.
Why don't you take the hike down a few times and attend some of the events down here to get a good feel for yourself. There's no reason that you have to take the jump without being able to cheaply come down once or twice a month. I live near Sunrise and often drive down to Kendall or as far north as WPB for some events. This is a good site for events and covers much of SoFL: http://www.miamitechevents.com
I talked about this briefly last month and it still largely applies: http://news.ycombinator.com/item?id=2545770
