I created an account at Mastodon: @cameron@camerondcampbell.masto.host. If you already have an account there, follow me. Right now I post there occasionally. So far I like Mastodon. It resolves what I regard as the main problems with Twitter: the ads, the clutter, and the incessant effort to suggest to topics or accounts to follow. The main problem is that there aren’t that many people using it yet.
If you’re wondering what Mastodon is, you can learn more: https://joinmastodon.org/
I’ll start posting more often if people actually show up there.
