No matter which way it goes it's not going to be rosy.
With Multiple Topics the Discussions are spread out more in different Topics giving a wide array of what goes on in the apartment.
With a General Chat that locks after 30 Pages. One Locks and another begins and over time you got pages filled up with locked Topics that no one can reply to. If a General Chat goes a Month then you so many pages that no one is going to go look at 100 pages or more trying to find one specific happening on a certain day.
Anyways a change was made so we'll see over the course of a couple Months what happens.
