I think stickied threads need a strong reason to be stickied; having six-or-so non-moving threads at the top of the forum isn’t great, especially when they’re prone to not getting regularly updated like the tools-and-tips one (that I’ve said as such before - and it’s only on 1 of the 3 pages)
I don’t think giant mega threads are great, and if the attitude is to just ignore them I don’t see the point in them existing - why have threads that are purely for seeking engagement if the majority of forum users will avoid reading it?
The better forum threads are the ones that encourage back-and-forth and present progress (either from WIP to Final piece, or artist development).
For the same reason, I think critique should be allowed to have separate threads so that it encourage feedback and present progress, rather than bunched together in a mega-thread where it’s likely ignored and forgotten.
Just looking at a few of the replies and they either receive a single response (good on those who do) or none at all. Whereas if it’s in a separate thread (like what SpicyShark tends to do) multiple users are more inclined to respond.
