I'm not on a computer. On a tablet kinda device. My right side shows whose on and who i've followed that is on etc.
In a conversation it tells me who's in there with me and the posts are very "long" hotdog style kinda. The right side telling me who's in the convo follows wherever i scroll until the very top right before a post is seen.
in a normal thread it doesn't do that, the posts take up the screen normally.
