I’ve been kvetching for a year or more now about how crazy it is trying to keep up with various social networks online.

The truth is, many of us have stuff we do at MySpace or Yahoo, some we might do on our own blog (either self-hosted or at TypePad or Blogspot, etc), and maybe another more personal journal at Xanga or LiveJournal. Then there are dating sites, as well as professional sites like LinkedIn. Plus the bookmarks you keep up with on Ma.gnolia or del.icio.us, and your pics on Flickr and Videos on YouTube. (Or any of the other competing services.)

But what about when you want to keep up with all of it together? And what about when you make a friend in one, but you want to share something with that friend on another?

Sure there are RSS feeds for a lot of it, for keeping up with one-way content traffic. But the *interaction* which is so vital and valuable for this new Web2.0 world can only be had when you login to each one separately.

If I had more of a code/development background, I’d just jump in and try to make something. But, barring that, I’ll just keep complaining until someone either 1) partners with me on the idea and we make a few million selling it to somebody (ha!) or 2) somebody just makes it happen regardless.

I wonder if these guys at Broadband Mechanics are onto something like this?

Broadband Mechanics: Our strategies

By establishing the notion of an ‘open social network’, millions of end-users will be able to move their personal contacts, groups and ‘social capital’ wherever they wish. They’ll be able to create relationships with anybody on any network, to send these new friends messages, create or join groups or post content – anywhere. This is the way the ‘social web’ needs to evolve – not locked up in old fashioned data silos – with vendors monetizing these captured end-users.

I know I’ll be keeping an eye out. But in the meantime, why aren’t there more startups trying to do this? If somebody can make an offline client for MySpace by scraping the site under your login and reconstituting it into a better desktop interface, why can’t a website do it, and do the same with everywhere else your identity lives?
