There are a couple of discoverability mechanisms, but it really depends on what you're looking for.

Usually people follow the network -- find one person that's interesting, see who they talk to, and go from there.

Another approach is to see what "interests" are popular and click through to see who shares those/is active: https://www.dreamwidth.org/interests?view=popular

But, TBH, there's a lot of happenstance and serendipity (or are those the same).
