Just to add my two cents on the bokeh issue. When beginning to post to this thread, I also looked up the definition in various places, finding that indeed, both ways of looking at it seem to be correct. The
artistic way that the background is blurred, and of course the specular highlights that in the vernacular, we've come to think of as bokeh.
I think about it this way when I'm posting: does my image's background have that indefinable 'something' that would cause a viewer to appreciate the background? Was that artistically blurred background something I strove for at the time I was choosing my aperture setting? (happy accidents are always okay too

) Is the background an integral part of the over all image? If so, then I'll probably post it.
When I post an image from flickr, if it's visible to 'anyone' there, I'll often also make the post here a link to the properties page back at flickr.
