Mastodon, via jorts.horse. I use it mainly to shitpost, and occasionally catch up on news.

PeerTube, via spectra.video. It was part of an effort to switch away from YouTube, but due to the abysymal discoverability, I am forced to concur that it hasn’t been doing well as a replacement. I now just use Grayjay to see videos, regardless of platforms.

For now, I use Lemmy via lemmy.cafe. However, when PieFed gets a stable app, I plan to switch over to it, probably via feddit.online.
