I set up a Google Calender to hold the different techie events in the Tampa Bay area. It has events for both adults and kids. I won't try to cover every single Meetup or user group meeting because those are easy to find and be reminded about. I'll try to catch all of the unusual and one-time events that are a little harder to find.
If you have events to add, send me a tweet @jonadair.
If you are interested in Microsoft technologies, check out Joe Healy's DevFish.Net site with many more Microsoft-centric events.
If you are interested in startup events, check out this calendar at Startup Digest.
The Tampa Bay Technology Forum (TBTF) has their own calendar of events they sponsor.
