Posterous is pretty cool. In addition to being a blog, it's a dissemination tool. If a post is created on the MGS Blog, a Posterous tool can be used to grab any pics in the post plus the title and an excerpt and generate a Posterous blog post which links back to the original but, more importantly, is pushed to Twitter and Facebook.
So, one blog post, after a few clicks, has three backlinks.
Hopefully the same 12 people aren't seeing it at each place, but that's probably the case. Still, it's a nifty tool.
