Craigslist is brilliant. Saw the founder of Craigslist on The Daily Show a week or so ago as the guest (or was it the Colbert Report? Don't remember). Either way, very smart guy! Seemed like he might be gay, too!

CL isn't as big in Tampa as it was when I lived in, say, Los Angeles. You could use it for anything in L.A. - hiring employees, finding jobs, finding roommates, buying concert tickets or anything else (like a quicker and easier eBay), and it's also a huge personals/hookup site.
