There are lots of interesting group accounts you can follow on here, they work like this:
1. Follow a group's account to see discussion of its topic
2. @ the account if you want to post to the group
3. The account boosts anything @-ed to it, be careful when you @ them so that you don't spam the group (spammers tend to be reported and blocked)

Would you miss Twitter if it were gone? What would you say at Twitter’s funeral?
We are researchers at University of Colorado Boulder conducting a survey about how people think about the role of Twitter in their lives, given recent changes to the platform. If you are at least 18 years old and a current or former user of Twitter, we’d love to hear from you!
Hey, welcome new people! 👋 Are you wanting to convince others to try Mastodon too?
Show them this video to explain what it actually is: https://tilvids.com/w/wx2iLhD3pTipbKFJKLyx5t
Tell them they can find servers to sign up on at https://joinmastodon.org/servers or https://fedi.garden and all these servers have promised to uphold certain standards (https://joinmastodon.org/covenant).
If they have any questions about using Mastodon or the Fediverse, they should take a look at https://fedi.tips or ask me directly.
