Recently active problems in twitterfeed tagged with update

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.

I have a locally-hosted RSS feed at http://funkatron.com/feeds/itemsofint.... Items there are set-up to be posted into my twitter account "funkatron" every half-hour. Twitter auth and feed validation both work fine. However, it appears that items aren't being posted, at least in the last 48 hours or so. Any hints?

Hi Mario,

Seems as if the twitterfeeds I have created a while back are not updating. I went in and changed frequency to 1 hr. I added some keywords. I parsed the feed. I checked the twitter connection. Those worked OK. But it still (after about 30 hours) shows the last feedpull status as March 28, even though there have been multiple feed tests in the last 24 hours.

feed is clarkcountytoday.wordpress.com/feed
twitter account is vancouverusa

Any ideas?

By the way, I tried to DM you on twitter (I follow you), could you please follow back. I am "homesights".

How long does it take to update on Twitter?
