Category suggestions

Some form of project announcement e.g. just announce, maybe with announce > libs (for new libraries/new versions), announce > tools, announce > PSA, announce > event... dunno how fine-grained we should be; alternatively, could flip the categories around, so that we have libs > announce, tools > announce, community > announce, etc.

Community/meetup stuff community:

General blog posts/articles of interest: discussion?

People asking for help, help. (many many examples.) (possible subcategories include code review)

@Ygg01 discussions about the stdlibs (i.e. including the satellite rust-lang repos) make sense on internals, although there's definitely a gray area.

Now that I've written all that, I suspect we shouldn't do subcategories for now, I think having at least community, discussion, help at the top level would be nice.
