I wrote a tool - previously prophesied in my "On Nim" post - that periodically polls gemlogs for new posts and sends digests of them over email. It has support for multiple users with different feeds. I think it's kinda nifty, but it's almost certainly buggy - if anyone tries running it and finds issues, please mail me at sunset@arcanesciences.com! This is alpha-quality software. I'm also likely to run a public instance of this if that would be something anyone would find useful - it has a Gemini frontend that allows user registration, feed management, etc.
