It's very interesting what the first topics are. There is a #conservatism with 8 members already, but you can't make #liberalism, #communism or #leftists. "The_Donald" is "coming soon".

(Edit: I must have hit a bug because I tried with a few names and my attempts just didn't do anything, but someone else did it immediately).

I wonder if this is like Gab, an attempt to make a more single-issue-politics-friendly variant of a popular site.
