There's tons of good stuff on this website. On a site like like paleonu.com, you can plausibly read (and re-read) all the articles. On here, the sheer volume makes it difficult.
If one wanted to suck the marrow out of the bones of paleohacks.com, but on a limited time budget, which specific threads should they read? Preferentially, hacks that changed your paleo behaviors in some way, or helped you address a problem you were having.
I also like the threads that just ask something like "hey everybody tell me your experience with X," and then there are about 15 answers. Even if those threads don't seem as "challenging" or "serious" I still get a lot out of them, and even if the question is something as simple as "what have you been eating recently?" I just like hearing about a wide range of experiences. Not that I don't like threads about the Krebs cycle; just that I also appreciate these other ones.
I would start with the questions with the most upvotes...
That's the point of upvoting questions IMO
I'm a big fan of before/afters, for motivational purposes
