Synchronize me

Just as I was about to ditch del.icio.us for Google bookmarks, del.icio.us beefed up their social networking. So now I want to stay with it rather than move to lonely ol' Google Bookmarks. But Google Bookmarks has some great features, so I'm torn. I wish there was a service that would synchronize all my public data between all these services. They all want my data and I'm more than happy to give it to them. Why can't I do this? This ties into my previous complaint that there's no way to import my Wordpress blog entries into MySpace. A synchronizing service would also help a lot of smaller services get the amount of data they need to develop and compete on a feature level. Ho hum.
