I post on mastodon and bridge to bluesky. That way I can reach anyone there interested in following me, but I personally don't have to bother with the site at all.
As someone trying to reach an audience, it's pretty much perfect. Each to their own obviously.
As a general rule, try to also include a description of who you are on your profile. If you're active people will check in, if you give some sort of description there they are more likely to actually follow you.
Usually when someone follows me I'll check out their profile, if they look interesting I'll follow them back. If their profile is empty I usually won't.
