Just a quick service announcement: it seems that Twitter, in their infinite wisdom decided to completely kill the old RSS feed style which was used by the vast majority of Twitter feeds on planetkde.org. Unfortunately, while it is still possible to get RSS feeds out of Twitter there is absolutely no way to convert the old feeds into the new style.
So we've been forced to remove all of the now broken feeds - which was done in this commit. For those who are affected - you can easily restore your feed using the new syntax: https://api.twitter.com/1/statuses/user_timeline.rss?screen_name=<name>.
A real pity that they have not even tried to migrate anything over or provide any compatibility what so ever - my apologies to those who are affected.
