I don't understand why programmers use github for everything, in particularly for lists. This should be a blog. Then you could easily subscribe to it, you could have a discussion for every single idea. And you wouldn't need several lists of ideas. The only thing that would be harder would be to edit ideas. Is this a feature that would make sense for blogging platforms? A combination of blog and wiki? But even without that, suggesting an edit in a comment would work as well as a pull request.
