There are many different ways to earn bitcoins, Starting from faucets and signature going through online methods in general.
Starting a faucet might be a beneficial way of making good amount of bitcoin in short time. But many people here never consider starting an own faucets.
Actually, I'm sure people here would never use the faucet to get bitcoin but the results are less good in my opinion and if already tried the signature campaign will definitely leave a faucet for a better income.
