“some more whitespace between the columns is needed”

You beat me to it. Not just there though, I think you need to be a bit more consistent with it’s use throughout. Some of the icons butt right up to the text, others have a small right-margin, then others have a bigger one. Some of the headings have a big top margin, some none at all.

The search form looks unfinished, with plenty of top/bottom padding and no left/right.

The blockquote style stands out a mile, shouting “look at me, I’ve got a red stripe”, which is inconsistent with the rest of the site.

Conversely, the main nav (home/tsg presents/contact) doesn’t stand out enough. Enlarging the clickable area on those links would improve matters, as would linking the logo back to the front page. To me, the RSS icon is less important than the nav and search, so I’d move it down the page a bit – and probably put the “What’s RSS?” link with it.

Personally I’d rethink the icons themselves too. The FamFamFam set a) doesn’t quite fit here, and b) is used heavily in a web app I use daily, so I’m fed up with it

As for the type, could you try something other than Arial? Perhaps Lucida Sans or Calibri (although the latter comes out smaller IME, IYSWIM, YMMV, HAND).

/removes hat, runs away sharpish!

I’m not feeling it with this design yet though – I might have been looking at it too close for too long, there’s a lot of typographic and grid detail but perhaps some more whitespace between the columns is needed.

Sorry, I couldn’t help it. Just giving cause to your preemptive defense
