Hey lyl,
I get the idea and the reason why most social media based forum (ie.Reddit) has this. However this isn’t something that’ll benefit users on jsp.
For trading, we really just use the search option to search for specific items in need, and sellers also use the search option to find users who are looking for particular items or services.
A majority of traders aren’t really interested in seeing which thread has been “hot” in many cases it is the thread that has been bumped the most or auction trades.
Also, contact a senior mod to add a poll so that we can see how the community feels about this.
