I already have a close group of Bitcoin Audible fans and we discuss and share a lot of articles, but I'm looking for a broader reach. Only about 25% of my articles come from the community and I'm specifically needing a place to get them from a larger social graph to bring them *into* the Bitcoin Audible community.

In other words, that's less what I need the broader social network for anyway, and will probably mostly be redundant. Xeeter has a very large network so it offers disproportionally better output in that regard.
