for the new tooters: feel free to make an #introduction / #introductions toot about yourself!
use hashtags for special interests or hobbies or whatever you're into, as they're pretty useful to help connect each other.
here's a great introduction by my admin if you're still feeling overwhelmed by how different mastodon is: https://medium.com/@GinnyMcQueen/toot-how-to-intro-to-mastodon-e5655bfa87d2
in addition, we also have picture descriptions / captioning built-in!
you can, and should, enter a description of the images you post (even #selfies!). sometimes this can feel weird and difficult, especially if you're not used to it
but much like content warnings, even a small bit of information is better than none at all!
