Tricky, because some people take down blogs because they no longer want anything to do with it. Are you going to resurrect things against their will? What about dead people? What about their relatives? All of that before we're getting into copyright and profits (for which I have much less regard).
Maybe I should add that I'm not trying to argue against "OSR/NSR Tabletop Roleplaying Games" being a group on the fediverse. It's just the groups I joined because I was following Todd on fedi elsewhere. 😄
Against splitting RPGs into OSR, DIY, Indie, Story Games, etc.
Here I am arguing against the split into the various sub "camps" of current RPG culture. I used to believe in this divide, too, but now I'm convinced the differences are just talked up and don't really exist except as tags, not inherently better or worse than tags such as "solo", "rules lite", "gonzo" and all the other ways of splitting it up. The tags remain important for some people to "find their crowd" but that's far weaker than saying that these are the most important splits in RPG culture.
My actual favourite category would actually be "64 pages or less for rules, setting and adventure"! 😅
I actually like the web page https://campaignwiki.org/rpg best. I wrote the code based on other "planets" – web based feed readers that just take all the feeds, sort articles by time, keep at most 4 from each blog, and take the 100 most recent ones. Everything else just falls off the bottom. It's really important for my peace of mind have no unread count. 😅
I run a bunch of web apps for role-playing games. I wrote some games, too. Mostly just to put my house rules into a nice document. One is my take on B/X D&D called Halberds and Helmets, the other my Fantasy Traveller variant called Halberts.
