Show HN: I've built a bookmark reminder for X, Bluesky, Mastodon and Nostr

I've started working on this project in 2022 and then shut it down after a few years. The idea was that I'm bookmarking interesting bits and then forgetting about them almost instantly, while I usually diligently check my emails and keep my inbox clean. Birdfeeder sends you a weekly digest of your bookmarks across these platforms so you don't forget about them.

I've recently revived it and added a bunch of features and new services. Mostly to get familiar with Bluesky, Mastodon and Nostr.
