Rodrigo,
I really don't mean to be negative, but the appropriate forum to discuss
the merits of the decision is in the topic open in wikipt about it. About
the form, using sitenotice for external social media reach, I can see a
reasoning to debate this here, but discussing if it is/will be effective
seems out place. This decision should be, and seemly will continue to be, a
community decision.
Excuse-me if I read too much into the message.
Best regards,
Chico Venancio
