If you don't mind me giving you some unsolicited product feedback: I think SemHub didn't do well because it's unclear what problem it's actually solving. Who actually wants your product? What's the use case? I use GitHub issues all the time, and I can't think of a reason I'd want semhub. If I need to find a particular issue on, say, TypeScript, I'll just google "github typescript issue [description]" and pull up the correct thing 9 times out of 10. And that's already a pretty rare percentage of the time I spend on GitHub.
