I'm going to say no to uniformity. Out of hundreds of millions of Buddhists, I suspect that one or two of them may have different needs than the rest.
Heck, even a single person may have different instructional needs over the course of their life.
As for reading about them online, I'd say that's about as bad as it can get. I think some of the members of this forum do a find job of proving that. I certainly suffer from that problem too, as my personal life doesn't offer time to participate in a community. Consequently, I have the most unstructured, crap meditation practice you've ever seen.
