I'm really glad you're taking the lead on starting a Sydney LW meetup! To get the ball rolling, I strongly suggest that you hold this meet-up unilaterally and without waiting for feedback on time/dates/location from others. The paradox of choice is paralyzing everyone. Just pick some details and do it. I've lived in Sydney before so I'll help by suggesting the details I would use if I were there.
Meet at the Sydney Fish Market and hang out on the wharf outside Peter's Fish Market from 2-4PM, Saturday, March 19th. Bring a small sign that says Less Wrong to set on your table.
Commit to being there every 1st and 3rd Saturday of the month at the same time until people start showing up. Bring a book to read in case no one actually shows up. If so, no big deal, just go a few more times like this until it gains traction. In the mean time, you'll be getting some good reading done so you win either way. This is how the New York and Berkeley groups got off the ground.
Good luck!
Don't commit to repeating it. That just gives people an option to ignore the first one.
Update: Well this seems to be a bust =/. Maybe people don't check the "new" section, only "promoted", or maybe the site visit statistics are deceptive.
Just saw here that Sydney has the 2nd most LWers of any city without a meet-up. So, let's have a meet-up!
Let's instant-runoff vote on the specifics until Sunday 6th, and I'll update the post with the verdict then:
1. Which date and time of the following work for you? Rank the ones you can attend in preference order
a) Evening of Tuesday, 15th March
b) Evening of Wednesday, 16th March
c) Afternoon of Saturday, 19th March
c) Evening of Saturday, 19th March
e) Afternoon of Sunday, 20th March
2. What kind of setting do you prefer?
a) Bar
b) Restaurant
c) Other (park for picnic, cafe, etc. Please specify)
3. Which area of Sydney is best for you? Rank the ones you could make it to.
a) City/Central
b) Lower North Shore (e.g. Neutral Bay, North Sydney, etc)
c) Greater West (e.g. Parramatta)
d) Inner West (e.g. Newtown, Enmore). Tempted to suggest the Humanist House in Chippendale, although I don't know what the deal with it is.
