I remember browsing this website a long time ago, and it looked pretty good.
But today, with 1080p monitors being pretty standard, the layout/colors look kind of inferior.
For instance, there is very little contrast in areas that matter beyond the basic color scheme.
Keep in mind, this is just my opinion and I don't expect you to change your website just because of me, but I think if the color theme/scheme had more shades of colors to it, text/things would be far easier to read, easier to locate, and keep track of.
What mostly bothers me is the home page for lack of contrast, but in general how blocky it is doesn't appear to make good use of the space available. I think with a fresh new look Daniweb would attract a lot more users!
(Sorry for trashing the website lol)
