There's been a lot of talk about MeetUp.com's decision to charge $19/mo to MeetUp Organizers, but what struck me the most was this email I got in my inbox this afternoon.
Your Organizer, Matt Jarjoura, sent the following message to
the members of The Washington PHP Meetup Group:Well, since they are asking me to fork up $19 a month for this
and PHP DC has barely gotten off the ground, I am going to step
down as organizer.Maybe someone will step-up and revive this group, otherwise it
will probably be frozen in time.-Matt
