The thing itself - Blogs.mu: http://blogs.mu/
Here's a quick intro to the concept:
Here's a community called Indie Films that I just started (probably for mostly promoting my own movies, but, I'll probably end up promoting friends' projects too):
It's less than bare bones now, but I can envision how that indie films blog network could be developed into a very useful marketing tool.
Another thing that my (or anyone else's for that matter) Blogs.mu sites can be used for is doing blogging-for-hire work for indie filmmakers & projects who do not want to blog themselves (don't like blogging, don't have the time, not good at it, whatever) but would not mind having daily or weekly posts getting published about their projects. Something to look into.
I don't know if blogging & for that matter indie filmmaking & distribution are ways to get rich, but participating in those activities definitely makes life more interesting, & certain film projects could turn into small revenue streams, & blogging & other DIY publicity will definitely help with that.
