the website of the future will be a wiki. Simple navigation, lots of content, but based on real impressions of your company by customers, partners etc. instead of propaganda from the company.
Maybe there's a tiny minority of companies for which that would work -- they'd be small, obscure, have a loyal fanbase, and almost never piss anyone off. For anyone else it's a disaster -- all you need is one disgruntled customer (or fanboy for the competition) with too much time on his hands.
