Alternative to pingomatic.com?

[DiscoStu]

I used to use ping-o-matic to ping multiple social services, but it's been dead for some time now. Does anyone know of any good alternatives to this? I've recently found Ping.fm and Addthis.com, does anyone know of any other similar services?

Here are some suggestions I found in another thread:

Great list, thanks!
