I haven't logged into orkut for a long time, almost since it first came out and the 'craze' began — but I had no idea until recently that such a thing existed. Scrapboy is a free instant messanger, but one with a great twist. It's no ordinary chatting, instead you could almost call it a 'mashup' — it let's you "scrapchat" through orkut. For example, it looks and feels like an IM and imports your friends list from orkut, but instead of 'chatting' allows you to leave someone a scrap entry and they do the same to you, and so on — Scrapboy tracks them like an IM session. Worth mentioning that all your sessions are public (hence, 'scrap entry').
