Microblogging Aggregators like Ping.fm

Hi All,
I was wondering if you can suggest any other Microblogging Aggregators (like Ping.fm, hootsuite, twitterfeed, posterous, etc)?

I have lists of TONS of Social Media site, but the Aggregators I found so far only update a handful of them.

Thanks,
Rob

I would like to add Onlywire in that list!!

Well - Onlywire looks different.
With Ping, for example, you set it up to connect to your Social media Sites....then,I have it set to grab updates from my Blog RSS Feed - and it spits them out to those sites without having to do anything more
