The forum is indeed open to all, but the impression I have gotten from reading this forum for a couple of years is that the most active or vocal posters are financially very well off. I didn't mean to imply I believed they are more active because they are well off, though that may indeed be a factor--I really don't know. I have seen posts now and then that suggest the poster lives an unusually austere retirement (so-called "Lean FIRE" types, perhaps), but they are not names I see pop up often. Rather, on a day to day basis you tend to see a concentration of the same names in many threads, and from reading their posts you get a sense of what kind of resources they have. It's certainly possible that there are others of more modest means who read the forum and participate in polls but for whatever reason do not post much in the threads. Anyway, just an observation about polls here in general.
