Twitter's RSS feeds used to be in the form
https://twitter.com/statuses/user_timeline/username.rss; then they moved to
https://api.twitter.com/1/statuses/user_timeline.rss?screen_name=username. Apparently this too will be discontinued, in March 2013 (i.e. this month!) and this time with no alternative way to get them.
Is there any app that generates an RSS feed from a Twitter timeline? This would be necessary for those of us needing to switch from the current RSS feeds.
Ideally, I'd be looking for an app that requests permission to view my Google Reader feeds and gives me a list of new feed URLs for my twitter-based feeds, but really, even a manual (one-by-one) generator would be great.
