How can one earn some Bitcoins with minimal skill requirements?
The most popular way to earn a bit of Bitcoins without any much skill is mining. The amount of coins one could earn is pretty small even with higher-end graphic cards, but through the use of mining pools and alt-coin mining one could get a small start in the Bitcoin world.

A website that offers small Bitcoin rewards for mechanical-turk-esque small tasks is CoinWorker. The skill requirement is minimal and the service provides value to people paying for the task.
