Let's see what other things I've heard called "silly fads"...
- Microwave ovens
- The Internet
- Blue jeans
- Autofocus cameras
- Digital cameras
- Photoshop
In truth, all of these things are tools... but when they first "hit the scene" they tend to get used and overused... people try to see how much they can push the given technology or item because it's new and interesting and they want to see where it fits in. At some point in time or another, excitement around the item dies down and some of the more ancillary or extreme applications die off.
For example... when the microwave came out, my Mom tried to make everything from hot dogs to cakes in the stupid thing. Nowadays most folks know that making a cake in a microwave is generally a disaster, but boy does that sucker cook vegetables!
Right now people are going gaga making all kinds of wonky images with HDR (and/or tone mapping)... (and what really cracks me up is when people make HDRs when there's no reason to) but there are actually some REASONABLE applications for this method.
For example...
(ignore the sensor dust, I keep forgetting to fix that

)
There's absolutely nothing wonky about that image except that it would have been technically impossible to capture the blue sky in the windows and still be able to see the interior... other than that, it looks almost completely as you would expect to see it if you were standing there.
As time goes by, I expect more people will use HDR/tone-mapping for this kind of application and the funky crazy stuff will become more of a side thing that people do more occasionally like they do with IR today.
Whatever the case, I think your sitting there and saying that [para] "everyone should explore and find their own way", and then dictating what ways are unacceptable is pretty silly. Maybe someone's style is all HDR all the time... who are you to say that's wrong?
