[Imports] How good can an import be?

[Muki Haklay]

So far there isn't a comparative study of the Dutch experience before 
and after, and it should be possible to analyse the data to see 
longevity pattersn. It's on the 'future research' list right now - 
Martijn van Exel and I discussed exactly this problem recently, but we 
still need to find the person who will do such analysis.
My hypothesis will be that imports doesn't influence contributions 
significantly. Nama Budhathoki research showed that other factors are 
more significant in motivating contributors, the Google Map Maker 
experience show that people are contributing even when data is present 
and the longitudinal analysis in the UK (which is now covering March 
2008 - March 2011) show that places that are mapped continue to evolve 
over time.
