I remember Homesick and John making this point when Sean unvailed a (possible?) new logo last week.
When I browse to DiS on my little Nokia thing it shows this site in arial rather than a serif font (I don't know why but I guess its faster) and I prefer it. I find the serif text hard to read. I like serif in logos and titles, though.
I realise the 'deadline' for site requests has probably gone but yeah: main site text sans-serif please. I think there were even studies done that showed it was easier to read, no?
