Credentials don't so much matter if you're doing startups -- you need to know some co-founders and you need to all trust each other to be able to make things.

But college helps a lot of other things. So:

If you end up at GT, I'd recommend looking into their Computational Media program. It's a lighter version of CS with extra media studies (games, films, websites, etc). You still have access to all the CS classes if you want them. I am of the (somewhat biased) opinion that you can craft a better startup education there.

UCF also has a pretty good CS/media program and is in Orlando, which might be easier for you.
