How to archive tweets now that API has changed?

Twitter shut down the RSS feed API, apparently in March 2013. Has someone figured out how to automatically capture and archive a user’s own twitter postings now?

Hmmm… I appear to have solved this myself. By going to pixsy.net and entering

.twitter -rss-u [enter Twitter user]

I was given a URL that correctly accesses my feed. I’m confused, because the Twitter developers blog clearly states that the API for RSS was shutting down in March 2013, but this worked for me just now. (I’m curious how the URL differs from what I was using before, but I didn’t save that when I updated my feed query in DT)
