Actually, most of BTC that I got from faucets were received as referral cimmission, so, I didn't had to spend lot of time. I agree with your point about waiting long time until value will increase, but I didn't had to wait - these BTC from faucets were more than my monthly wage at the moment when I received it.
Years ago, faucets are high, and the first signature campaign was run in the forum in June 2011 had high payrates too, at 0.1 BTC for three-month period.
