20 Ways To Aggregate Your Social Networking Profiles

I have just noticed that one of my friends (Beth Kanter) had added the del.icio.us this article:

20 Ways To Aggregate Your Social Networking Profiles

 

It starts off with:

"In an inspired blog post, Jason Kottke said that social networks aren’t helping us organize; since all of them require different credentials to log in, they’re just adding to the noise. He just might be up to something there. It’s getting harder and harder to remember all those logins, passwords, and most importantly to remember which of your friends are using what network."

 

Of the 20 applications it mentions I have only used Explode and MyMashable. I think we should try some of the others. If you have any experience of any of the 20 listed or others can you post to the MeAggregator group?
