I feel like such a nerd.
I LOVED raindrop.io when I tried it yesterday. So I made a copy of my sync-pinboard #WordPress plugin that works for Raindrop.

And I also made a copy that will sync Mastodon posts from an RSS feed into a WordPress custom post type.

Neither of these will end up on the repo. But feel free to use, fork, etc.
All part of making my own "digital garden"!
