I think what's interesting about this site isn't just the experiences themselves (he talks about not liking a particular guard, for instance), but watching the range of emotions that an inmate in Pinellas goes through from when they are first received to being sentenced (he has been incarcerated for a year now and is still waiting to find out if he will be shipped off to prison for drug trafficking).
If you want to know more about life in Pinellas in particular, his blog is a great resource. If you want to read other inmate's stories here is a Pinellas County Jail informational site.
