I just opened a profile at The Internet Archive. I think it might be a good place to post irregular podcast-like audio; most of my other social media platforms aren't big fans of audio, and I don't want to post bland, one-off stuff to Bandcamp or SoundCloud. It also might be useful for bland footage of places I visit, sort-of like my Panoramio site, but for video.
There's nothing there yet, but it exists.
