Yeah making a list of faucets is a good way to earn some free bitcoin :)
I would suggest you check out bit kong, its a gambling site but it has a really good faucet that pays 1500 satoshi.
You cant withdraw that, but you can get free gambling credits.
I am earning some decent money with this one - https://bitkong.com/en?r=mj2hAIam
Is it? I'm not banking much on referral programs I suppose it could help, I saw your post on bit kong and checked it out, i'm not much into the gambling aspect i'm cool with collecting a few Satoshi that'll eventually end up in my personal wallet though.
The min withdrawal is 400k satoshi.. if you refer enough people who keep playing or keep claiming on the faucet you could get this every week.
Depends on your goals. I have been doing internet marketing for about 15 years, thats how i earn my money so i am onto these things like a pitbull on a poodle :P
If you want more bitcoin, yes start getting referrals :)
Actually i noticed in your post too.. your first link Bitcoinker doesn't have your ref url in it, might wanna fix that :)
