1$/hour is VERY bad pay, i probably wouldn't even do faucets for 1$ per hour only, as there are many better ways to earn, much faster and better paid than that.
and for 2$/hour i would do faucets, but nothing else, and for 8$/hour i would do lots of work.
Wow!!! you are choosy.. For others that is big money already... 1$ per hour if you have no job means a lot to you, you must be very rich..

But anyway, as long as the tasks for 1$ is easy and reasonable and could be done in an hour or less, we could take it, I my self I would do a simple task for that like sharing something on twitter or in facebook...

1$ an hour is very nothing in my country. You would not be able to live from that at all. I would need to be paid atleast 6$ an hour to have any use for the money.
For 1$ an hour if i were a student maybe I would do it, like post twitter messages etc what you said. But for 6$ an hour I'll do much more intensive work then i would do for 1$.
