Pretty much how it has been for me for both lemmy and mastodon. I think I went to the sign up page for mastodon several times in the days that it was blowing up, and I just didn't know what server to pick, and even when was at the point of "I will just join one" I still had issues picking one because a lot of the site names sounded untrustworthy, or like specializing in a community I am not really part of. Like the one I ended up on gave me vibes of being for people into astrophysics.

I am also not sure if people would read the rules pages, but more skim them for keypoints in maybe 30 seconds. Think went that route with lemmy that I skimmed the rule of a potential instance and saw the rules and went "nope, not for me" and was back to step 1. Though this time I was more familiar with the rodeo and have made more users on more instances
