You raise some interesting points and as is true with most photography, it really is up to the photographer/artist, IMHO. That said, my preference has always been to convey more a desription of the image (subject/location, person/title) that would allow someone 50 to 100 years from now to know who/what/when/where. On a personal leve, I do not care for 'cute' names, but again it is up to the person making the image. If looking at it does not tell me anything or if it is one that I am looking at to hang on a wall, the name does not matter - if I like it, I would still purchase regardless of the name.
Just another 2 1/3 cents worth (used to be 2 1/2 cents but inflation).....
