I've also created a Twitter account for Shadow and maybe some other velari (or I guess it's X now, sigh): https://x.com/ShadowTheVelari
You can follow if you want, but it's almost empty for now 😅
Tbh I have absolutely zero knowledge how to operate there effectively. And since I don't want to nag people to follow on every post here on e6ai and in general trying to not bother people needlessly, that account could probably stay like an echo chamber for a long time. Still, I intend to post there regularly since it doesn't require anything special like tagging.
