No, Alex Wagner, you're not correct - the concept of the #manosphere's been around for yrs (Google or Twitter search it), it's just been re-coined recently as #manoverse by someone who either couldn't remember the real name or is just messing w/us.
Actually I've never heard it called the #manoverse before.
And I prefer #manosphere - visually easier to see what's happening there & it's less likely to be mispronounced.
Potato, potahto, I guess.
But not really. :)
The downside is now we have to try to follow and post about both #manosphere and #manoverse.
You know what they say: divide and conquer.
