Its time you export / import Delicious bookmarks to Google Bookmarks as Yahoo! Delicious might shut down and all your Delicious bookmarks saved over the years may be lost.
Google has created a Delicious to Google Bookmarks tool, which helps you import your Delicious bookmarks to Google Bookmarks. If you’ve merged your Delicious Account with your Yahoo! ID, the import process uses OAuth, or you can sign in to Delicious with a Delicious account.
Your Delicious credentials will not be stored or used after this import process is complete. Any data you have stored in Delicious will not be edited or deleted by this import process.
Now that will surely get a lot of Delicious users out of Yahoo and into Google Bookmarks, which is getting better integrated with Google tools.
