When BTC started, nobody had any and it was worthless, so it was right to give away thousands of BTC to make it popular. All that has changed. Now that BTC's worth something, now that companies are building on BTC, now that serious business transactions are made with bitcoin, it's about time for faucets to adapt.
BTC is real. It's money, and you've got to work to earn some. I hope all faucets will disappear in 2015. Faucets are hurting bitcoin by making some people believing you can get it while doing nothing sitting in your home. No, BTC isn't like that, and it shouldn't be any easier to get than any fiat currency. Even for small amounts.
New potential users of BTC need a way to get their hands on some BTC, even if it is pennies or less.
Not only will it introduce them to learn and test out how wallets, addresses, private keys, transactions, and etc work,
but it will allow them to participate and explore BTCs potential in a safe, non-scammy, or potentially dangerous (localbitcoins meetup) way.
One of the problems with adoption is that average people have a hard time getting their hands on it easily.
Faucets, I believe, are still an important factor in adoption.
Faucets will always exist (even around 2140) until/unless Governments consider them money transmitters or gambling, IMO.
