My Data, My Identity, My bookmarks, My pictures

This news just out.
Yahoo Bought Delicious.
Now I am not sure how I feel about this. Now they own two of the major tagging sites.
These are my tags on my photos and my bookmarks. How can we get out of pattern giant identity silos buying up other services? I want an integrated Identity on the web that I manage weaving together tools and services that are useful to me not just handy cause they are in one of the mega silos.
Hopefully they will avoid the major faux-pas that happened with Flickr where they asked users to to enter a yahoo ID instead of their existing Flickr account.
