One of the few lacking features that Del.icio.us doesn’t have is a better organization/sort ability. Viewing by tags and viewing only the most current popular items. What Delicious needs to do is organize only the most popular items in the past hour, 8 hours, 24 hours, week, month, or even all time. This is what Popacular does. It’s a great place to find topics for blog posts, find the most popular of the past days topics, or even see what items are creeping towards being the most popular website of all time.
If you’re a fan of Digg, you should like something like this, although it’s much more stripped down and it lacks the obnoxious comments.
They also offer a Twitter app, that does the same thing. Displaying the most popular items for tweets.
