Is the concentration of bubbles in detergent a measure of anything?

[BarnOwl]

That is, if the detergent generates lots of bubbles does it mean it cleans better than one that doesn't generate mucho bubblitos?

Are the bubbles merely an appealing but meaningless feature?

For the hell of it, put a little bit of Dawn, or some other detergent, in a pot and turn on the hot water full force. Get an idea of the prevalance of bubbles. Go ahead and count them if you think it's important, we can wait.

Next...

Thoroughly rinse out all the soap, or even better, use another similar pan and put in the same amount of detergent. Now, use the 'shower' feature of your faucet and see the phenomenal increase in bubbles. (If you tend to be impressed by inconsequential shit, this is absolutely guaranteed to knock you out. )

So, that's my question. Do more bubbles help a detergent clean better?
