Week 2 into using Clubhouse, I am much happier with the rooms I'm getting in my hallway. Suggestions in the thread:

Under the
search bar are the themes. Pick a subtheme and read bios of the people listed in area. But don't base choices on the number of someone's follows, because a lot of people chase the follows. They're bloated strawberries.

When in a room that you like, check out the bios of the people there, whether on stage or in the audience. It's likely that they will attend similar events in the future and those rooms will become more visible to you if you follow them.
I also UNFOLLOWED all the automatic suggestions that CH made for me when I clicked on my interests the first day... and that helped get rid of a lot of irrelevant rooms. Hope this helps.
