Seems that I can explore the 3000 users at (actually only those have more than 10 followers, which is just a few dozen). Can I somehow search those 2 million users? I am sure some of my friends are already here, but how can I know it?

The advantage of is that "everybody" is already there. With Mastodon I must first invite my friends and (more difficult) convince them to do the extra step of creating yet another online account.

After reading this I decided to try it once more. Looking forward to meet my friends here soon.
