Hey, just wanted to introduce myself! I'm AJ Jordan. I'm an Invited Expert on the SocialWG, I maintain pump.io (among other things), and I [filed an issue] against Mastodon to adopt one of our standards, ActivityPub ;)
I also have another Mastodon account at @ajordan, though that instance is a bit of a fixerupper at the moment. I'll get to it Real Soon Now™.
