Welcome to everyone migrating from #twitter i hope y'all stick around
but to set some expectations
while mastodon is advertised as a twitter alternative it is not a drop in replacement and if you expect it to be you'll just be disappointed, there is no algorithm to find things for you, and you will not become famous here
however if you can i would highly recommend trying to stick around for more than a month, it takes patience but when you find your corner it's quite nice here (if you have a following on twitter i imagine it took a months or years to get it on twitter, don't expect mastodon to just give you a following any faster)
and you don't really need to become famous anyways here, I'd argue it's a better experience with a smaller community here
in my experience despite being much quieter than twitter it's easier to find people who'll actually interact with you here (i appeared out of nowhere a few months ago with no existing following and i still got more interaction than i got in the year i was active on Twitter)
it takes patience, but i highly recommend putting in the patience and sticking around for a few months before leaving because it didn't give you enough attention fast enough
if you expect too much you'll be disappointed, but if you temper your expectations a bit you might be pleasantly surprised by the community you find here
also to those that joined mastodon.social or mastodon.online (or even mstdn.social) i highly recommend looking around for a smaller instance sooner than later
it might sound counterintuitive but I've found it's actually easier to find people who'll actually interact with you on a smaller instance (bigger than 100 smaller than 10000 is probably the sweet spot)
since on small instances things move at a pace where people can actually find you, while posting on the big instances without any existing following ends up feeling like posting into a black hole in the noise
and even with mastodons migrate tool it's easier to move instances earlier than it is to move later
