My very honest opinion (please don't hate me) is that Pets.ca (no, not the forum) looks like the website equivalent of a set of lego from the 80s.
The primary colours, the boxiness of everything, the overly cluttered-tiny-text-everywhere-you-look madness makes me just not read any of it.
Please, I beg you, no more boxes or primary colours.
Please make navigation of the site less overwhelming. Though I don't love the aesthetic, the Urban Carnivore
site makes good use of tabs to organize information.
Also, just a random suggestion, everything looks nicer with good photography. If articles could be illustrated (with a photo) and the front page had a big, beautiful photograph(s) I think it would really go a long way to make the site stand out and be nicer to look at.
Oh, and also (I promise to stop after this
) the font! Something a bit more, um, round, would be good and using fonts to differentiate between titles, area headings, etc. would rock.
Hope that wasn't obnoxious.
