got this idea from another (non-photography) forum that i'm a part of:
first, look at the statement the person who posted above (or before) you said. you respond to it as either 'true' or 'false', then come up w/ another statement for the person below you.
for example:
the post above: The person below me is into photography
your posts:
1) TRUE
2) the person below me is . . .
and continued on....get it?
let's get it started...
the person below me owns more than one brand of camera (digital or film)
