The following is a high level checklist of issues that should be explored on a site. We will be drilling deeper into each part of this checklist in the weeks to come, providing examples and tips and suggestions for speeding up how these things are checked upon, and expanding upon the checklist itself as we go along. We will also be shuffling around these issues to prioritize them, and indicate which things should be checked first, and so on.
We will also try to include sources and documents about these different issues as well.
If you have any suggestions, questions, or advice to add, please either let me know directly @chriscountey, or use the comments.
