I hate the current trend for websites to have about a page's worth of information spread over about eight pages' worth of space. I'm used to seeing it on startup websites, where it doesn't bother me so much because I expect those to be trendy. But I'm recently seeing it infect websites of old school geek projects that I feel should know better. This is one example and the new emacs website a few days ago was another.
I'll allow it. Lisp in general (and Common Lisp in particular) desperately needs better marketing, which unfortunately is susceptible to the vagaries of fashion. If dressing it up a little makes it more attractive to the next generation, then mission accomplished.
So no, good marketing isn't an argument for this kind of website, if anything I think it's one against.
