Yea, is too bad wikipedia is The One.
I guest is a effect of the One Of A Thing internet effect that have created Google, Amazon and many other services. I wish the internet worked with a rule of two, or tree. Not good for humanity that it seems to push a single website for one purpose over many.
I would not punish ourselves too much over it. Like theres something really bad in neerdoom or geekdoom. Is a internet thing. Facebook is not a nerds/geeks thing and is also member of the One Website club.
Nerds have created healty competitions like Gnome/KDE vi/Emacs, where the competition was friendly and even cooperative at times.
