McLean Mashingaidze-Greaves is the man behind RapSpace.TV, a hip hop social network based out of Canada, that was recently profiled by Matthew Ingram:

One of the interesting features of RapSpace (which launched a beta version in November), is that prospective MCs with a webcam don’t have to spend the time saving and uploading their video. RapSpace grabs the video as they perform, encodes it and stores it, then generates a code so the performer and others can embed the video in a web page. And if a rapper doesn’t have their own soundtrack or "beat" to rap to, they can pick one from the RapSpace library. The technically ambitious can even use the built-in Web tools to customize a track. McLean says rappers will also soon be able to compete head-to-head with others on the site in real time video contests.
