@darius you may want to look into this article I've recently written: https://blog.platypush.tech/article/Create-a-Mastodon-bot-to-forward-Twitter-and-RSS-feeds-to-your-timeline

By now this guy, written with the same code described in the article, brings me all of my favourite tweets and RSS feeds to my Mastodon doormat: https://social.platypush.tech/@crossbot.

It uses #Platypush as a backend that takes care of the boilerplate (namely, polling RSS feeds and Twitter sources and translating everything into Mastodon API calls), but the logic of the bot itself can be squeezed in 20 LoC max.
