OTOH, if you build a playlist manager for playlists everyone can add to, you make sure nothing anyone adds will break it…

99% Invisible - An excellent design/architecture podcast

20k Hz (“twenty thousand hertz”) - great show about the audio that pervades our daily lives, from notification sounds to movie special effects, passing through game sounds, sound history,etc.

Imaginary Worlds - in their own words, “ a podcast about science fiction, fantasy and other genres of speculative fiction”.

All three are done by professionals in their respective fields, exceedingly well researched, and with superb production values.

I’ve used thunderbird pretty much from the start, for the last 20 years or so. The UI was looking a bit dated, lately, so I’m really looking forward to this. The next thing we need is better performance (I may suffer more than most as I have literally hundreds of thousands of messages and dozens of folders on the imap server). Fingers crossed!

Not even that. I’m getting serious Usenet vibes (from the early 90s, not the thing it has since devolved into). Even the decentralized paradigm with independent servers syncing with each other is conceptually similar (although I’d bet NNTP was a quite different protocol than what we’re using now).
