That’s a terrible justification, and I would question if it’s even true. Is there anything to support that conclusion or is it just a guess you’ve made?
Because I don’t buy it. There is no time limit for discussions. One can take as much time as they like to enter text on their phone. Also if they’re motivated by the discussion they may take the time and make the effort to write thoughtful replies.
Finally, there’s no reason that users visiting on desktop computers won’t make equally shallow remarks. Shallow online discussions have existed long before smartphones existed.
