Twitter with an RSS feed is a waste of crawling traffic.
Suppose you follow 1k accounts, you have to subscribe 1k RSS. What a waste. Twitter's core functionality was based on how to aggregate all 1k updates into one feed.
There's a tool built by friends in the IndieWeb community called https://granary.io that allows you to produce a single RSS feed for lots of handy things - like your full feed, specific lists, or specific people!
