Social networking sites are being created with the same intentions as myspace, these are known as myspace killers.

AOL plans on building a social network on the back of AIM, which will pre-populate your AIM friends as your social network friends as well. Functionality will be similar to MySpace - with blogging, photo and music widgets available for integration.

This site talks about two new Myspace Killers. One is called 'Lostcherry' that is sold as an edgier, more anrchistic myspace. The other is 'Smutvibes', which is effectivly an adult myspace based in Jamaica where adult content is not only allowed but encouraged.
