I'd like to be able to autopost from my wordpress site (private wordpress.org, not on wordpress.com) to multiple sites with one plugin/hack from within wordpress. I'd like my posts to be able to be auto-posted (linked to) on facebook, identi.ca, twitter, posterous, etc. without multiple plugins. I've looked everywhere for a good plugin and they all seem to be site specific (for example just a twitter plugin). I need a one-stop shop like posterous, but since i have my own site i don't want the links going to posterous when they could be coming back to my official site. is this at all possible as of yet? if not, someone should step up and code it. thanks!
You can try dlvr.it
you just need the rss of your blog and it will be published to facebook, linkedin, googlebuz, Twitter and more....
I've been using it for months
