I think it is interesting to read the first 4 posts on Grognardia. Quite prescient 10 years ago.
Starting with “What’s A Grognard?” is important to set a certain stage, that is the wisdom brought to the table by the experienced within a culture.
Then on to “Pulp Fantasy D&D” and “What is Pulp Fantasy?” details the increased desire to incorporate Appendix N influences when playing tabletop RPGs. However, these were posted in early 2008, (a month after Gary Gygax passed away BTW) and this is still a hot topic.
Lastly, in “D&D in the News” JM totally calls the fate of 4e and sets the stage for (why I believe) 5e becomes a success despite all the other potential escapist distractions. That is, by returning to some of the core roots of D&D in earlier iterations. The one irony in this may be the same technology which brought an alternative fantasy escapism (and signaled a downfall of tabletop RPGs), the PC and the internet, have served 5e quite well in the form of virtual tabletops, Twitch, and YouTube which perform quite well with lighter versions of D&D.
