I made this awhile back as a Meower[1] bot that posts RSS feed updates to groupchats, and reads RSS feeds, powered by Extractus' Feed Extractor[2][3]. My friend's groupchat uses this bot to post updates to his blog, and he says that it has been working out great.

Looking forward to your feedback and suggestions!
