There are some good, and bad examples here... Bokeh is pretty subjective, but.... It's really not just showing off a limited depth of field, or creating a substantial out of focus area around the subject. Bokeh is how that out of focus area is managed and display. It's a quality to it, not just it's existence. Good bokeh keeps the background highlights from distracting from the subject.. More often than not, it mutes or softens the background to form very even, low contrast flows or blends of colors and objects... Often soft, or silky background appearances... Even a lens with potentially good bokeh can give a shot with bad bokeh if the photographer does manage the background or foreground properly. This is where previewing with the DOF button, or at least understanding your lens and depth of field performance helps...
However, all that said, what I like, you may not like, and the other way around... That old beauty is in the eye of the beholder...
I'll be the first to say I'm not that great of a photographer, and quite often struggle with the patience required to make a good photograph, instead of a "pretty picture"... So, I don't have any especially good examples to share... But, it would be unfair to say there are good an bad without showing my feeble attempts up to this point...
Bokeh that I like.... The photo is beyond noisy and can use some serious help in that area, but it was an ISO 1600 shot indoors handheld with a 100mm lens... But it's an example of smooth transitions from focus to out of focus, no highlights, etc...

No bokeh... Which in of itself can be good... Any wider aperture lens, especially macro types that can give good subject isolation... The absence of bad bokeh can be a good thing...

I don't seem to have many good examples of good bokeh in my shots posted online yet.. Guess I'll take this as a personal challenge to come up with some..
Anyway, liked a lot of the photo's previously shared... Even if not always good examples of bokeh...
