How can one earn some Bitcoins with minimal skill requirements? This issue came up during a chat on this answer to a question asked by a new Bitcoin user.

Lets say I am new to Bitcoin and don't want to go through the hassle of exchanging money for coins quite yet. I don't have much of marketable skills, so I can't offer my services. How then can I earn some Bitcoins with minimal skill requirements, without any long-term commitment or investment of any type?
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.
