Tigerlaw, RobT, SPFXted and Gambit post a lot and I wouldn't say I learned anything new about fixing my pins, but reading their posts is one reason I log onto this site because I find it entertaining and enjoy most of the things they post about pinball. Congratulating Ted, Kwikimart, and others on 100 K Karma points were funny threads.
Sometimes people post because they want to vent. Case in point the latest Stern debacle. Those threads got derailed, lots of hyperbole, but I think it was great for people to have a place to vent about feeling wronged. I really believe somebody from Stern gauged how angry their customer base was, and how their distributors were feeling heat, so Stern was quicker in their damage control because of it.
I also feel that the huge threads with complaints about Stern's lack of X-men code reached Stern as many of the suggestions were implemented and some prominent posters on here became code testers. The 7k thread was a mess, but it was the thread that brought attention to the Aux. board problems, wolverine fix, and other things.
Personally, I wouldn't mess with Pinside too much as the growth this recent year has been phenomenal. Designers and new company owners are posting inside information on new pins and their businesses, because they know they are reaching a huge number of pinball consumers.
Incremental change could be a good thing, but I personally wouldn't like to see huge sweeping changes that might alter what caused Pinside to be what it has become. Robin has done a phenomenal job and the site is the best site for pinball.
