Libraries and Linux

A thought just occurred to me - Libraries and Linux have a lot in common.

• They are both free (although there are some you can pay for)
• Sometimes it takes time to find exactly what you are looking for
• People that use them are passionate about them
• You get critics who cannot understand why they are used and say things like why not pay for (books/software etc) instead of getting them (legally) for free?
• It is actually easier to use them than it first appears (although libraries can be a tad easier all round)
• If you have problems with either you can ask for help and with both you can sometimes get stuck with a curmudgeonly expert who can't understand why you are having difficulties but who will help you (although jargon may be used)
• Both are used far more than a lot of people think

These are just some of the similarities - if anyone has other ideas please feel free to share them in the comments and I will add them at a later date.
