A good way to get started is to identify some of the nexus accounts, people near the center of your social groups on Twitter, then look for them on Bluesky. If you find them, you can follow them -- but consider also going through their lists of who they're following, and who they follow, to find more of your crowd. Think about whether you really want to follow them, instead of automatically following them. Consider repeating this step periodically as Bluesky grows, because you may find more of your people have snuck in.
There was a web site called Fedifinder that tried to find your Twitter crowd in both Mastodon and Bluesky. It's been down the last couple times I've tried it, alas.
LifeHacker referred me to a Chrome extension I haven't tried yet, which tries to identify your Twitter people on Bluesky so you can follow 'em: https://chrome.google.com/webstore/detail/sky-follower-bridge/behhbpbpmailcnfbjagknjngnfdojpko
