Anyway, I found a plugin for wordpress that sends out blog posts to ping.fm. Meaning your blog post will get sent to all those sites as either an update or microblog. Of course there are size limitations, so best to be sure the opening line of the post includes a nice description. To be honest, I just found it yesterday so haven't had time to experiment with it yet, but it definitely has potential.

Of course there would be a few things to take into consideration. If you're running autoblogs you're not going to want the content being sent to all your friends and family as an update on Facebook or where ever else. But for personal blogs it would be perfect if you don't mind sharing your posts. Another great thing is, it works with forward dated posts also.
