I was thinking about that too. It seems that in some ways, Twitter has already become what RSS has been trying to become for years. It's much easier for people to understand "following someone on twitter" than it is for them to understand "subscribing to an RSS feed in an aggregator." Obviously there are some pretty big differences in the purpose and functionality of the two technologies, but maybe there's something to learn regarding the terminology used to describe RSS.
