Reminder to new folks here, like my good friends @foxesafloat .
Write an introduction, use the introduction hashtag, plenty of people follow it, you'll get some nice boosts and engagement from it.
There is no computer feeding you what it thinks you'll like, you need to engage with people and people need to engage with you. So fill up your feed by following some folks.
Search doesn't work unless you use hashtags, people can't find you, so make sure you use hashtags all over the place.
Because there's no machine to boost posts, make sure you Boost(retweet from the old world) to share the tweets you like with others. A favourite over here will show the user who wrote the toot you liked it but do nothing for their engagement with others so help them out with a boost.
If you're posting stuff that others might not want to see, like my habit of terrible political hot takes, use the CW button to hide the post behind a content warning.
There's far better guides that this kicking around, but if you're new here, this is a good starter for 10.
Welcome to a more relaxed, better engaged environment.
@foxesafloat what flavour?
