People can talk about whatever they want. The power of message boards is that topics that don't interest people filter down into the abyss and those that get a lot of attention are at the top.
There's also a feature you can use to mark things as "read" if you don't want to read it. For me, that's most of the recruiting threads. I just don't expend much energy on that part of the board because it fluctuates so much and frankly just not much interest of mine until we land a recruit.
I also tend to avoid spam posts about ergonomic chairs that show up before the moderators get to it, discussions immediately after an ailment or death as to whether they wore a seatbelt or not, and anything related to Iowa.
May your OT threads capture the attention of many, or fall into the abyss. Happy posting.
