You're correct, it is very much a matter of annoyance.
My complaint here is that there have been a lot of "general" threads for seemingly insignificant topics, and the title has become incredibly overused. General threads, in my view, should be used exclusively for topics that will have constant, varied conversation. The first "General" we had on this site, obviously, was the first Pony General, and it was created because the users here were getting sick of every other thread being about ponies; there was a need for one, so it was made. Next came Homestuck General, which was also made because there seemed at the time to be a need of one.
My point is this: general threads around here seem to be made with the intention of making them staples of this forum, such as Pony General, which leads to the creation of such threads on insignificant topics. We can simply create titles that do not include "general," and add the subtitle later. A perfect example of this would be the thread on Legend of Korra
TL;DR: we can just start a thread on a topic without "general" so there aren't 15 different small-time general threads, and add it in later if the topic inspires more dialogue, so the designation retains its value.
Crimson: yeah, maybe a little.
Bob: I considered posting this in Site-Related, but defaulted to the General section because of increased visibility.
