When Winamp was popular Macs were <5% of the market. I hope they release a version for macos. I don't think the current developers own the IP to Macamp.
Not so much (with some little exceptions) for actual podcasts [1], but rather for managing my collection of various radio comedies – its handy being able to sync them over to my phone together with the rest of my music collection, but by manually setting their media type to "Podcast" [2] they don't clutter up my regular music library, I get the handy unlistened/listened visual indication, and it remembers the playback position in case I can't listen to an episode in one go [3].
[1] I was never that big a podcast listener, plus now that my mobile music player hardware has its own network connection (because it is in fact my phone) I can download episodes directly there without having to go via my computer.
[2] No longer possible on Mac in the post-iTunes age, and the successor Podcasts app apparently doesn't support manually adding files as episodes to it.
[3] Okay, so you can turn on remembering the playback position for any file in iTunes, i.e. even regular music files, but that doesn't work with my Android phone.
