WYSIWYG = what you see is what you get, very common...
As for divils original comment about this site being "graphically intense", Id say thats mostly true. While the graphics are small, mostly 1k-8k, there are 84 of them (on this page). That means 84 connections back to the webserver assuming cacheing isnt working which, as divil pointed out, it probably isnt.
I dont think "graphical" means just JPG and GIF images. I would guess divil meant this website is very user interactive friendly with dropdown menus, hover images, quick reply boxes, etc. Those things all take space - 100k of pure source code for a simple 1 word post (I tested). There are certainly optimizations that can be made - using a separate CSS file rather than inlined styles for example. Some of these have been brought up in private - helpful comments that we all appreciate.
As for the original question: Why are there fewer people? I think someone (Bob maybe?) answered this awhile back. One factor is that its summer and "kids" arent in school as much, asking the questions they normally do.
I would like to hope that as time goes by, the more common answers or FAQ type questions can be found easier and hence less of the common posts. With a robust search available here and being able to search Google for posts, I would hope more people find the answers they need rather than post a question thats already been answered.
I dont think the original questions has much value by itself, other than for curiosity. I propose a different question: Does anyone feel like theyre not getting the answers they seek? If only 10 people used these forums but all 10 always found the answer they sought, I think the forums would be a success. As it is, I see most questions getting answered and generally in a very quick response time (within a day or so).
The other important question would be: Does anyone feel like theyre afraid to post a question? If so, why?
