I interpreted it first to mean functional programming, then remembered what functional means to most people, then remembered that this was HackerNews, so I had to check.
This is our first meetup. If you like functional programming and booze then you should definitely attend. We will choose a venue after getting a rough estimate of how many people are attending. Thanks.
It seems, based on your free-form questions, that you're checking to make sure people have a genuine interest in functional programming before letting them into the group. Am I correct? Kind of reminds me of http://freehackersunion.org/
