Ki is a user on social.targaryen.house. You can follow them or interact with them if you have an account anywhere in the fediverse.
More or less picked this instance at random - what do most people base their choice on?
@mikel I was all confused about the signup process and just picked the only familiar thing I recognized. Targaryen.
@ratapaloma Same feeling of confusion for me. I have friends who even found twitter too confusing, so I can imagine this will seem too difficult for most users for now.
