Delicious is one of the biggest social bookmarking services. It provides powerful functions to syndicate information from service in form of RSS feeds. Unfortunately they overdid it with feed internals and in current state it sucks.
Fortunately it can be fixed and I did just that with simple Yahoo Pipe.
Delicious tag feeds
Delicious provides two types of tag feeds:
If narrowed down to specific topic there are not much bookmarks that get popular so recent feed is more active and interesting.
I had subscribed to portable tag and very soon (after umpteenth link to Portable operating systems on Lifehacker) I had noticed that instead of recent links feed serves recent bookmarks literally. Every person adding any link (no matter if it is present on delicious already) with that tag gets in feed.
Looking into it showed that Delicious is using some kind of unique identifier as guid (you can refresh your knowledge about guid with my post on RSS internals ), tied to user who made bookmark.
Yahoo Pipe fix
So I made simple pipe that filters duplicate stories from feed and reassigns real link as guid. There will still be duplicates but your feed reader will (or at least should) correctly determine them as such and only display new items.
- Go to pipe.
- Type in tag.
- Run pipe.
- Get as RSS.
