If you touch the avatar next to a thread, it will show their name. Like I said, lots of noise. Every thread listing had four of who started a thread, on one line. I have cut that down to one. The only thing I removed was who posted last, but if you have posted onto a thread, it still shows that on the left OP avatar, also clickable / touchable to see.
Whilst IMO it might be nice to see who posted last, that doesn't tell you who posted since you last read it, that is shown when you click into the thread. So even that is useless information.
A lot of forum setup is very old, dating back 30 years... and we have to move forward with more modern standards, but not dismiss the forum values. I am trying to find that balance, is all.
