Quite frankly, I think most threads here get made that seem to me to be vehicles for getting into arguments, rather than just passing on information or asking for assistance. Rare is the thread where the poster says "Here's a problem I've found in D&D with my game, and here is what I did to fix it"... because usually that thread gets several responses of "Okay, that's cool" and then thread ends. There's nothing to discuss-- a problem was highlighted and immediately fixed. Then the thread drops from the front page and is never seen again.
Or the other rare type of thread is someone who has an issue, asks for assistance, and then receives several suggestions from other posters... and the person says "Okay, that helps! Thanks!" And that thread also ends because the question was asked, and the answer was received. And again, POOF!, off the front page.
Instead... what threads usually are is someone who makes a statement about something they have an issue with... and are not asking for suggestions on to fix their problem, they just want to vent. And they vent away. Which is fine! <snip>...
At the end of the day... if anyone makes an open-ended thread that doesn't end after like six posts with either an acceptable answer being given to a question or just a handful of "Good job!"s... you are going to get people arguing about it.
