@retronianne @ely_peddler It's the thing people who haven't signed up complain the most about (e.g. on Twitter or Facebook).
Note that it's not possible to track funnel exits for signups for this accurately because 1. people may go to e.g. mastodon.org for different reasons and then never do anything and 2. it's decentralized so there's people trying to sign up on another instance, and that instance might be invite only etc. and then they never try again.
