Just wanted to quickly chime in and say I'm really grateful for the work of EveryMac. It's a great starting point for learning about any Mac, but just like any internet resource, it's good to use multiple sources to be sure.
For 99% of the time, I've found EM is correct. But for that 1%, I still have MacRumors.
I think we all need more gratitude for the resources available. It's hard to understate the value and importance of having wiki-style websites for newcomers, even if they're never going to be perfect. And it takes a lot of work to make these resources in the first place.
Another source I like which hasn't been mentioned is LowEndMac. It's especially enjoyable reading about people's PPC solutions 10-20 years ago, but it makes me jealous that they had access to so many parts and CPU upgrades back then... alas... at least we have cheap SSDs now.
