hi,
a collegue made me stumble upon a german user page with a couple of interesting notes concerning wikimedia participation: http://de.wikipedia.org/w/index.php?title=Benutzer:DrJunge&oldid=9642776...
there is quite a lot of statements why the author thinks the current wmf and wmde suggestions for increasing participation and image filtering are "headless" and will not lead to any success. and, there is one idea which i find very appealing:
to increase female participation, drjunge suggests to implement "post-it"s. they can be placed on any position into wikipedia pages, and are only personally viewable in a first step. later the visibility might be extended just like with other social networks. one funny side-usage of these post-its is that they of course can be placed onto images one does not like.
as i am not female and not non-participating, i'd wonder what you think about such an idea?
