@plantsmydude a good way to get rolling on #mastodon is to do an "introduction" toot (oh yeah, posts are called toots :) ).
Basically just a toot with the hashtag #introduction, some text about you and a list of hashtags of what you're into, looking for, etc. Click the #introduction hashtag to see some examples.
(hashtags matter a lot on Mastodon because it's the primary way of finding things, as you'll see).
