Why is this project not popular?

I've been wondering why this project isn't more popular.

I think one reason might be the topics assigned to the project. When I Google "C++ event library", eventpp is the first result.

I would recommend adding "observer-pattern", "design-patterns" and "callback" to the project's topic.

@Sosukodo Thank you for your interest in the library. I updated the project topics.
Regarding the popularity, I'm not really sure. eventpp seems like a very good library though.

I suppose both have different use cases so it's apples and oranges to me.
