I was already not very impressed that they were bought by yahoo years ago, as I thought that yahoo! is not the right place to host (I used http://del.icio.us, with the dots, since 2005). I was and am also a pro user of http://flickr.com and wonder if my huge collection there would be wiped clean in 2011.
Just a side note, I hate the "from yahoo!" part of the logo (on both sites). Well, they should have done that much earlier, and I hope that some companies with big muscles could save them. I really don't want to switch boat.
