I'm feeding my Twitter account with my del.icio.us bookmarks via Yahoo Pipes. This solution seemed to work quite well until a few days ago. As a matter of fact twitterfeed keeps importing the rss entries of my delicious-through-yahoo-pipes rss feed over and over again. Thus every bookmark is being posted at least twice (or even more).
Any suggestions?
Edit: It seems as if shortening the URL using tweetburner is the problem. Actually I'd like to omit a switch to a different shortening service because I like the way I can keep track of my posted URLs using tweetburner.
Thanks to the guys at Yahoo!, del.icio.us feeds should now work again. Apparently twitterfeed.com request were throttled, but our IP addresses have now been whitelisted, so del.icio.us feeds should validate and succesfully post to twitter.
Thanks Y!
PS: no word from pownce yet, who also seem to throttle/block twitterfeed requests.
