@yarmo @kev sad truth from multiple occasions that I had with people is: people seem overwhelmed by the request to chose their instance. Always being afraid of making the wrong choice. It wasn't different for me. My first toot talked about Mastodon being the loneliest social media I've ever experienced. Things worked out, but facts are, telling someone got to "example.social" and sign up. Makes people a lot more likely than telling them select one of those instances.
Go ahead, ask people on the street for their email address. Most of them will be: yahoo, gmail, microsoft, and probably some older regionally popular providers (due to phone/landline/internet contracts or similar).
It's amazing how little people (want to) decide on the internet. They just follow what's popular and "free" for the most part and stick with it. That's not choice, that chance.
This is my personal microblog. It's filled with my fun, joy and silliness.
