[HOT] OSM Community Surveys

Hi,

I think before proposing who is leading what, having an open discussion
about what a survey about HOT Activations should encompass and what to
analyze would be a good start.
There is for sure a lot to learn from Haiyan activation but please let us
not forget there are other Activations to learn from. Haiyan is quite
exceptional by the massive response, over 1,500 contributors, due to the
fact it was a huge natural disaster. Conflict-based disasters are generally
less covered but the baseline data is not less really needed by the
Humanitarian organizations. I focus my voluntary time on this kind of
Activations and finding ways to improve the response and the number of
contributions (thanks again to everyone who has participated) is really a
key.

Sincerely,

Severin
