Diigo, the bookmarking service that in the past automatically sent copies of your bookmarks to Delicious, just sent out a tweet saying that they are connected to Delicious again. Last week, that automatic back-up process was stopped.
However, I bookmarked some sites ten minutes ago with diigo as a test, and they have not yet been bookmarked at Delicious. Perhaps it just takes them awhile,or perhaps it’s just not working.
Is it working for you?
