I don’t even think of this as a favorite, because it’s more like a tool. One that lets me find out about all kinds of groups and meetings the area that I can go to.
I still have a special fondness for its younger and cheaper and not as successful relative, meetin.org, because that’s the one we used when I met my hubby.
But for today’s world, Meetup is the way to go.
There are still the occasional floundering groups that look interesting but don’t have any meetings planned, but there is usually a good selection of options for a geek like me: code groups, walking groups, free events, writing groups.
You just have to be brave enough to go out and meet up with people you might not know.
Because eventually you might meet your future spouse, or employer, or best friend.
