post 2 ping.fm plugin that's compatible with WP 3.2.1?

For my personal blog, I’ve tried 5 different plugins that claim to be capable of taking my recent posts and putting them on ping.fm …. but none of them actually claim to be compatible with WP 3.2.1, and when I tried them, indeed, they were not compatible. PingPressFM looks the most promising but even the developer says you have to do some workarounds to get it working with the latest wordpress. He doesn’t say what those workarounds are, just mentions he knows people got it to work. Anyone got any ideas here? Suggestions for plugins to try as alternatives?

Is there a plugin that lets you pick your social networks to post to in the same way ping.fm allows you to pick?
