Well, as for changing the site style, that is not at all being planned here, only exploring the option of other coloring styles, for fun. Such a thing would obviously be low-priority, but would be something that could get the creative juices flowing. As I really don't do much for the site outside of management duties, this would be a nice little feature I could add in, myself.
As for promoting better threads and whatnot, this is in the works in a couple of ways. We are revamping how badges will be styled, and have not yet found a consensus. This is being planned as a reward for good threads, among other things. We're also exploring different ways of promoting good threads, and how/when we'll be making the reputation worthwhile for users. Ideas we have had in the past include a member spotlight, Staff-approved thread spotlight, and contests.
Any ideas you have on this subject will always be welcomed, naturally.
I envisioned "AGH MY EYES THIS IS UGLY" to cover that field, actually.
Exactly the thinking that fueled this idea for me. It can be quite fun, and doesn't hurt anyone, so why not? It is not like I, whom doesn't exactly do much for the site, have anything more productive to do.
This was actually an idea of mine I was going to keep under wraps, and possibly explore further on my own if this idea gained traction.
If this was done, it's be purely optional, as to not offend those that do not celebrate that holiday. Imagine us making a Christmas theme, and forcing it on everyone, even if others practice Hanukkah or Kwanzaa. Not a great idea, though possibly ok if we offer many optional ones.
