Personal experience is what makes this site great.
If it wasn't for us all sitting around here and talking about personal experience, then what would be the point?
We would just make a book list of things to read and classes to take.
Personal experience is what we have- and its great to see all the viewpoints of real people- not just what we read in books or areas of expertise. (OR some random profound and original idea that we've just invented. In which case we'd be at the genius convention, not here.)
I do agree that quoting personal experience for an argument or as gospel can get awfully annoying! But, I guess that's just the nature of these kinds of discussions. (In my experience, anyways !!!

)
If we were only allowed to talk about these great broad views that we've developed or had some area of expertise, then this site would be a pretty desolate land. (And a boring one at that!) We go to work and school to talk about things that we know for fact, right? Why not spew off some opinions and stories for fun?
(Excuse my dogma, by the way. I know this sets typologycentral back in it's broader mission to achieve larger social ends.
