The World Wide Web is far from perfect, but I believe most of the problems people experience with it will be solved over the next five years. All of the problems except one, that is.
Most people seem to think throughput and access are the big problems to fret over.
Others believe that it's the threat of censorship. In fact, the biggest problem is the permanence of a site, or the lack thereof. It amazes me just how often you see this message during a single Web browsing session. You should find a link all right if you do a nightly test, but it may turn out to be a new page having nothing to do with the original context of the cited link. I see this all the time.
