I used to go to maps.yahoo.com and tv.yahoo.com with ease and comfort, knowing I'll get what I want quickly. But no longer.
I am on the lookout for a simple TV listing and a simple map, no Ajax required, or frankly, not even desired.
Web design seems to go through "fashion" phases. I recall (years ago now) when "everyone" had to use Frames - the funny part being that Frames were intended to solve the same problem that Yahoo is trying to "solve" here. The hardest part of design (and I'm not about to say that I'm an expert in this area) is knowing when something isn't broke and doesn't need fixing.
