80%+ of private events I attend are hosted on facebook (nearly 100% of social ones.) Every gig I attend I find out about due to Facebook (easier than reading a print gig-guide.)
Same. There really needs to be a good alternative to manage and discover events in your area, but most will probably fail due to the missing userbase/users' reluctance to switch to a new platform.
Some organizers/venues in my area put you on their guest list and have lower entrance fees for people who are "going" to their Facebook event. The only way I see a switch happening is if they agree to only offer those rewards for users of the new platform. But some of them are already showing dissent and setting up their own mailing lists/group texts, so I still have hope!
