IMO it makes much more sense to do the opposite, and follow mastodon posts in the UX of a RSS reader.
I personally haven't been liking any content aggregation outside of RSS/reddit because I can't take the timeline model of unrelated things being streamed to my eyes without context. I tend to want to specialize what I read or otherwise I tend not to remember it or appreciate it as much (for instance I'd typically scan through news-like nodes during breaks and read art/science/in-depth feeds after work, but something that mixes both makes me uncomfortable).
But I do have a "people" node in my ttrss instance that aggregates from social network sources/blogs/shaarlis. Gives the best of both worlds, I think.
