Boompa is a social network and wiki for car and vehicle enthusists. The site enables visitors to upload pictures of their rides, write how-to guides on aftermarket modification and find news and info about vehicles down to a specific model level. Built by Dave Snider and Ethan Lance, who previously helped launch TV.com and MP3.com, the site sports an AJAX-powered user-submission engine. Boompa caters to car lovers young and old, as the hot rod crowd chats it up with high schoolers who are into the import scene.
