If people want them, great... but leave them off by default.
I'm a grognard, but I like sites with less graphics, less javascript, less flash animations, less "cutesy, eyeball-grabbing stuff" and more <i>written content.</i> Pop-down menus annoy the heck out of me.
Secondly, I am rather opposed to javascript in general. I just ask myself, "why on earth does this guy want to run code on MY computer?" I frequently surf with javascript turned off - because I don't know what some code monkey might want to run on MY computer. If you're going to do dynamic content, do it at the server with php or asp or jsp or cfm or any number of other SERVERSIDE methods rather than client-side methods - IOW, don't do stuff on my machine with javascript. Yes, this means you can't have cute little drop-down menus. I don't like them, I don't want them, and I don't need them.
Maybe it's just me. But I'm REAL touchy about who gets to do what on my machine. I don't need any self-installing hotbars or worms or other such niceties, thank you very much. Not that I am suggesting that you are trying to do that on ENWorld - but because I don't know about other sites, I try to keep Javascript off unless my "surfing" for the day is just hitting a few trusted sites.
If others want that, fine. But don't put it on for me by default. Make them exercise a positive choice to do it rather than ramming it down other peoples' throats. Come to think of it, I guess it's kind of like smoking to me - I respect your right to smoke, but please respect my right to clean air by not smoking around me. I respect your right to javascript, but please respect my right to surf without it by not putting it in as the default.
Come to think of it, I'm REALLY a grognard - I almost never touch the mouse, preferring to do my surfing by keyboard as much as possible. Perhaps that's why all of today's fancy-shmancy pages annoy me - with the pages and pages of code, I can't easily "tab" right through the links to hit the one I want - I never know where the next "tab" will take me. Heck, I even still play Quake III with no mouse. :b
