I've added a couple of tips to the coder wall, but it has left me wanting for a FAQ, and I've been wondering why. Today I realised why:
Anybody can add anything to the coder wall, even tips that are plainly wrong, or tips that have already been added, but just re-woreded (too many tips will make it difficult to find the good ones), and outdated tips will stay on the wall. Hopefully, the voting system will eventually sort out the good ones from the bad ones, but still, I find an FAQ would have the following advantages:
• A filter by the code maintainer, which can choose not to publish something wrong, or ask the author to re-word it
• Avoid duplication. If you find a tip/faq that you think can be worded better, you submit a pull request the same way you'd do with code.
• Old, out-dated tip, which are no longer relevant and possibly wrong for the newer versions, can be retired.
The coder wall reminds me of the old FAQ-O-Matic, which were never very good.
