I don't know why you're demanding that I explain a claim I never made and don't agree with.

I'm not communicating well. I'm saying, "sure, Wikipedia's UX is clunky, but it obviously does work".

You should read downthread; other people have taken a closer look at Danny Sullivan's real experience working with Wikipedia's processes. This isn't a good case study to make a stand on. Give it a few weeks; Wikipedia will inevitably do something genuinely dumb we can get outraged about. It appears not to have here.

That's just the old "success forgives everything" argument. It's a tempting argument, but that's also the primary mechanism by which success leads to failure. Wikipedia works, and is completely usable, by committed and dedicated nerds. Maybe even the dumb ones that work at the gas station.

Yeah, this guy was probably wrong, and this particular subject probably isn't notable. Wikipedia still could have given this guy a better experience in the process of figuring this out, and writing this guy off as worthless and not worth listening to is just arrogant and unproductive.
