Let's be clear: Abstract art and Surreal art are not just weird, bizarre or left field (whatever that is). And they don't both go in the same box together. And none of this matters if there isn't going to be any attempt at clear definition or curation. People will still stick stuff wherever, at which point genre becomes irrelevant as a means of finding something. I see that in several genres.

Putting aviation and transportation with travel fails when one looks at what's actually in the travel gallery! Some pictures of places, a lot of pictures of people, some cars, some other stuff... It's all a mess and I still don't envy anyone the task of cleaning it up. Besides, aviation and transportation manage to stay on target more than maybe any other genre! Sure, there are some head-scratcher entries, but they are very few in number, especially compared to what I see in some of the other genres.
