nice list.. after a few days.. i've obtain.. 0.00112561 BTC through some of these various giveaways.. kinda pathetic 
but whatever!!!
but whatever!!! And yeah these free sites and stuff are minuscule, but hey, free (fractional) bitcoins! Something to do while sipping on some beer saturday night 
There ya go. I remember a couple years back, I would ask myself why I bothered using sites like this to get such miniscule amounts like 0.05 to 0.1 BTC per day.
It wasn't worth much back then with BTC valued at less than $3... much lower at the start of 2011. Do you think I regret that few minutes of clicking per day now?
But that isn't the main point of this list:
What good is it if one only gets very very small amounts?
