I think faucets should be for fun and for exploring this beautiful technology, but not at all for making a living.
Also I hear pretty much things about profitability for third world people. I don't think so. If somebody already landed in this forum and is reading and understanding what's said here, he would find pretty more profitable things to do around the internet than with faucets. (freelance for example)
Depends what your skill set is really, there aren't many places that will pay you anything just for clicking buttons. It isn't a life though really, but if the average wage in your country is really low then it could be an alright interim step. For instance the minimum wage of Bangladesh is $68 a month, with bitcoin faucets available you have to wonder who would take such jobs.
