I had to go take a look.

An instance admin with 1,200 posts only, that sounds low for someone in a leadership position, and there since Jan 2018. I have been here for 6 months, and have 5,000+ posts.

Some pretty graphics, but I think she has varied interests (as shown by links in profile) and the mastodon instance is just one of many.

Not judging the instance, but just some comments from first look. I had not heard about it till now.
