[Wikimedia-l] What community initiatives have made an impact on editor engagement?

[Federico Leva (Nemo)]

The recent community initiative with the highest impact I can think of 
is surely what Platonides and other members of the global (technical) 
community did on pt.wiki. Platonides noticed a configuration error on 
pt.wiki: CAPTCHA was required for all edits since 2008. The error was 
fixed in April. <https://bugzilla.wikimedia.org/41745>

Fresh stats produced by the WMF show that in May and June this produced 
a decrease of overall vandalism (or rather, of reverted edits) with a 
shocking +58 % increase of productive edits by IPs and +23 % for 
registered users. It seems pt.wiki may see the end of the decline after 
many years. :)

Discussion is ongoing on how pt.wiki will address this growth. Part of 
the community may think that "nao estamos preparados para crescer".
