Get a subscription to The Family Handyman magazine. There's a decent amount of content on the website, but much more in the magazine which you can get for like $12/year. The This Old House website has good how-to articles and previously aired TV episodes, the 'Ask This Old House' segments are very good.
Black and Decker has a good set of books for plumbing, electrical and general repairs.
Manufacturers websites and brochures provide good information for specific tasks (ie: how to install shower membrane) and correct tool usage (ie: which blades to use for which type of material).
For trade specific information, you can look up the code handbooks for the particular trade. The trade organization websites usually have some good information, but some is pay-walled content.
For any project check multiple sources before going forward with it. I would recommend this especially if you are using DIY blogs that are published by people with little to no professional experience.
With all that being said, would anyone be interested in a website for learning the basics of using tools and as OP put it, "the broad strokes of DIY stuff (carpentry, wiring, general tool knowledge, etc.)"?
I have been considering putting together a website that is essentially a "teach yourself DIY" course/guide/tutorial.
Ideally, I would have a section that gave a primarily introduction to the basics and a "project planning" type component that would guide through the steps of your project by providing the necessary information.
If this is something people would be interested in, I would really appreciate any feedback.
