A parallel came to mind when reading the comments about the scale and
budget of the bids for Wikimania 2014 (which will be in London). The
opening ceremony of the Beijing Olympics 2008 was a tough act to follow,
and the Olympics in London 2012 was opened and closed with some panache
on a much smaller budget than Beijing.
Wherever Wikimania 2015 lands, it can be a fine event, that is community
driven, with all that you would expect.
