last year a system was set up to do some website stats for the participating countries centrally, Piwik. 

I was wondering, is there still an interest for this, is someone still managing this? (the problem arises when the first answer is Yes and the second is No :P ).

I transferred the piwik ID's to https://commons.wikimedia.org/wiki/Commons:Wiki_Loves_Monuments_2013/Progress , only countries that participated last year have such ID's currently. 

See https://commons.wikimedia.org/wiki/Commons:Wiki_Loves_Monuments_2013/FAQ#Can_I_track_the_visits_to_my_country.27s_website.3F for some more info about the Piwik setup.
