At the risk of appearing cantankerous, this thread irritates the hell out of me. What is the point of it? Essentially, "I know something you don't". Well, yes. No doubt you know lots of things I don't, just as I am very likely to know various things you don't.
All right, a thread that says "Who else knows the work of XYZ?" may not be compelling, but sometimes we learn about a new photographer whose work we like. Turning it into a low-grade quiz seems to me to add nothing.
It's rather like those 'What is it?' pictures, shot from odd angles or very close up, that appear in magazines from time to time (and have for as long as I can remember). My reaction to those has long been, "WHO CARES?" Either tell me something useful, or shut up.
Please don't take this as a personal insult, just as an observation on a particular style of thread -- and I'd be interested if others feel the same way about 'teasers'.
