Me, in July 2009:
So that is why I use Twitter’s favorite feature to help me save links for reading later.
For at least four years I've been subscribed to the RSS feed for my favorites on Twitter. That RSS feed is now gone. One of the features I found most valuable on Twitter is now gone and I can not complain, send feedback, beg, nothing. It is simply gone.
This is painful. App.net and Tent.is are looking more and more viable. At least with them I'd be a paying customer and I could write in to complain.
