actually this has already been discussed among the moderators quite a while ago, and it's been agreed that it's not necessary, and would not go towards simplifying the use of the forum for all members, which is the overreaching goal. there are many ways to filter content, and it's easy enough to skip over the silly threads in the lounge if you aren't interested in them ; the "silliness" prefix makes that even easier. among other things, the lounge often serves as a less intimidating entry point to the forum for new or inexperienced members while they are learning about the technical questions, and we want new members to feel welcome and comfortable here.
there are plenty of different forums here for all ebook related topics ; anything not concerned with ebooks that you would like to discuss can find a home in the lounge, including serious discussion about not specifically ebook-related topics. everyone is welcome to start a discussion there on any topic.
serious discussions about books can be had in the reading recommendations forum, about writing in the writers' forum, about formats, devices, conversion etc. in their respective forums.
there is plenty of room in all the forums here for discussions about any topic you are interested in. conversely, there are plenty of ways to avoid topics which don't interest you. please feel free to join in or not join in any discussion, and to start your own threads about any topics you'd like to discuss, including in the lounge.
