i've been following this since you first posted it, and have watched it change quite alot. i haven't really commented because moberemk has really hit the nail on the head about most things he's stated and you've actioned them very well.
all in all, the layout, presentation and usability of the site is up-front pretty nice, clean, easy to use and pretty darn good.
my ONLY gripe is a really nit-picking thing - the 'links' that sit just under your main banner. well, i thought they were links cos they look a bit like links but they're not. also, 2 of the 6 items shown here are not anywhere to be seen in your 'real' navigation on the left hand side. i'd say do one of the following:
1) lose the part i'm on about totally
2) extend the part i'm on about to cover more of your subject matter and less of what's not anywhere to be seen
3) make sure your nav has Pascal and .NET in it.
4) actually turn them into proper links
i like what you've got so far though for definite
Cheers
