I’m going to collect a few notes on my second attempt to try out Mastodon.
The first time I was unable to find people I like to follow. Simply searching, as might work on Twitter, failed me at the time. This time more people are announcing their Mastodon handle, perhaps it will be different.
I put the full address in the searchbox. The address looks identical to an e-mail address
firstname.lastname@example.org. I hit enter, and the top hit allows me to follow the account right away.
I just found out that Mastodon has an option to prevent people from following you, unless you allow it. (I discovered this when I tried to follow somebody in vain.)
