Why Doesn’t Google Buy Delicious?

So, I need an easy way to grab a url, and drag it to one of my groups. Google needs a reason to make me use Google Plus.  This seems like a no-brainer.

Currently, I use my Delicious Button in my Bookmarks to keep track of links.  But how much more useful would that be if I could also share it and choose what circle to drop it in from that button? I could see a link and ship it to my Relaborate circle, or my softball circle, or soccer circle, or even my personal circle.

It seems like Google+ isn’t going to win in the short term on the “status update battle.”  So, maybe they could win on the “indexing links battle.”  That seems more in line with what Google is good at anyway.
