my favorite are the people that think FB is the only form of communication these days. "oh, you didnt know about <event>? i put it up on FB..." how about you just email it instead? if you want me to come, call me...
I'd agree with you if you were talking about yourself and 1 other mate that wanted to see a movie.
I'd borderline agree with you if you were talking about a group of 3-4 mates, but only if you're talking about something with a set schedule (i.e. Band X plays at Venue Y) and only if you also IM with the others.
Even then, you're still that guy that doesn't want to make things easier on everybody because... um... because you don't like it. Or something.
Tell me, what's easier:
a) Create a new event -> Invite everyone on friends list or everyone who's likely to be interested -> whoever wants to go RSVP's -> Fun
b) Individually call/text 25+ people to let them know something's about to go down
If you can think of a single logical reason why we should not leverage technology to make these kind of things easier then I'd like to hear it.
