I was going to keep my trap shut, but now that someone else has spoken up....I, too, was put off by the word “Colloquy” when it became part of the new heading. The word has its place; e.g., in serious articles and editorials. It can also be used sardonically, such as when a writer wants to highlight the inanity of a conversation between two high school girls by, with mock seriousness, referring to their chatter as a “colloquy.”
As part of a discussion heading in this website, however, the word is pretentious.
By the way, what’s wrong with “Forum”? It’s a good, solid meat-and-potatoes word.
