I joined Twitter on October 12, 2006 (only a few weeks after Facebook).
I joined Diaspora on October 12, 2011.
I joined Mastodon.social on October 7, 2016.
This October, to celebrate Elon Musk buying Twitter, I created another mastodon account on chaos.social, and intend to finally make the fediverse a regular part of my umwelt. UPDATE: I did.
I posted this in October 2022 during week 2538.
For more, you should follow me on the fediverse: @hans@gerwitz.com
