OK, it seems the WMF is decided - based on a (imho biased and pushing)
survey of 119 people, without waiting for the experiments that Esino Lario
is executing right now, the WMF has decided the future of WIkimania. You
can find the info here:
Given the three options offered, all suboptimal, it is unsurprising that
people choose something like this. But if you want a fair survey, the
'outcome' should still be compared with the status quo (which may be
preferable to people): semi-rotational scheme, every year with some level
of bidding possibility. Because even when you take this survey as your
basis, the differences were not that big (61 vs 52% in favour for biannual
vs fixed rotation every year).
Anyway, check out the page, there are some interesting thoughts out there,
and I'm looking forward to step two after Esino Lario, when we know the
outcomes of the experiments there.
