This question:
Google Calendar alternative for an NGO who wishes to publicly share an activities calendar
which is somewhere in the convex hull of SF, SR, SU and maybe WebApps, has been closed as off-topic. So, first, I think it kind of fits the site scope. But - if it doesn't - which site is it a better fit for?
Note that I'm not asking for a software product, I'm asking about what an organization might do instead of having a Google calendar and sharing it publicly.
