While chatting with TG13088 in the IRC #gridcoin channel, he said and I quote.

"Faucets are a source of starter coins for Noobs ... Actually there is little incentive since far too many people look at them as a source of "free coins" and are constantly running them dry ... the intent is to use them to get enough to send your Beacon and then "stand on your own two feet" once you are off and running. Hopefully once you get established, then you can donate to help other people who are starting out."

Meaning it's the freebies hunters that run the faucets dry, I hope when they are "established", they will donate back to the faucets, so that, newbies will have coins for their beacon advertisement?
