Re: [Wiki-research-l] long in tooth: highly active editors are 1/3 fewer

[Mateus Nobre]

It seems like a sad projection.

If you allow me to, I would call it ''the editors disenchantment''.

The editors start, paraphrasing the first e-mail, as ''growing cheerful
teenagers''. Then, comes the maturity in the project after a couple years
in.
But the ''adulthood'' isn't a new phase in the Wikipedia, the mature phase,
as it is supposed to be.
It's the end.

We're kept by our bunch of ''teenagers''. Why ''adults'' go away?
