I mentioned the typeface "comic sans" in a recent post as an example of bad web design - a bad web designer will often use a lot of comic sans. Anyway, we did a bit of googling and found the following two sites: Ban Comic Sans Comic Sans Appreciation Society Although, in the interests of impartiallity I should point out that 99% of the links on Google are to anti CS sites such as 'the curse of comic sans'.
There's a time and a place for this font and in general this place is not on your web site - unless of course, you are a cartoon character. A company website is like a robot salesman out in the world 24 hours a day selling your company, you'd really want him to wear at least a smart jacket. Slapping comic sans around willy nilly is like dressing him in an old t-shirt with chilli sauce down the front of it!
If you want your website to give a good impression, hire a reputable web designer with a proven track record of quality sites which are similair to your requirements. On the other hand, if you're not bothered about your worldwide ambassador's demeanour, get your nephew to do it in frontpage - and don't hold back on the chilli sauce!
