I have been wanting to do something similar. I like the idea of trying to shoe-horn every internet thing I check into a Mastodon stream.
But instead of just using 1 account talking to Mastodon to post, I was going to make it ActivityPub. If it were AP-enabled it would let each RSS feed could have it’s own “identity.”
I’ll post it here once I have it working :)
Very curious! I typically want to go the other way (from Mastodon to my feed reader). Most Mastodon clients make it quite hard to “read everything”, so (for a subset of accounts I follow) I use Mastodon’s native RSS feeds to get all their posts in my feed reader, which allows me to read every post at my own pace (without notifications).
uniquely funny in that it basically clones the feeds to mastodon at https://email@example.com. we can complete the cycle by reading that rss feed from mastodon as well!
