Meetup Growth Summary September 2015

As the number of groups increases on this list the data becomes more interesting and the rankings more competitive.   We added 3 groups this month, and for the first time 2 of them are not from the Meetup site.   First, the Shire (Manchester, New Hampshire) group which claims to be the oldest meetup in USA. Second, Free State Bitcoin Consortium, and third Bitcoin Meetup Switzerland which makes its debut at #5 in the rankings.  Welcome to the monthly rankings.  If you are part of, or know another group that should be on this list please let me know in the comments.

Here is the link to the spreadsheet on Google docs: (the filtered tab is probably the easiest to view, set the date at the top and sort by growth % Z→A for best view) https://docs.google.com/spreadsheets/d/1FBCAMXzmfNE9bWneQK-Bah5eBS2iq507hVoX-QVN238/edit?usp=sharing
 

Always interesting to see which meetups rank the highest each month, we have Bitcoin London (the smaller of the 2 London meetups) taking the #1 spot for the first time with 36 new members and just over 7% growth, well done.  The always high ranking Bitcoin Wednesday Amsterdam moved up 4 spots to #2 with 60 new members and 6.2% growth.  Taking spot #3 was Barcelona Bitcoin Community, 36 new members for 5.5% growth.  They moved up 7 spots from #10 last month to #3 this month.  Again this group is always growing quickly. 

This month saw the San Francisco Bitcoin Meetup pass the London Bitcoin Meetup to become the second largest meetup group on our list at 2,516 members.  The largest absolute number of new members added was Israel Bitcoin Meetup (#10) with 67 new members, great job.

Notably 4 different meetups; Stanford Bitcoin Meetup, Israel - btc entrepreneurs, Bitcoin Budapest, and Bitcoin of South Florida saw their memberships shrink by 2 members each this past month.  What happened there guys? 

Big moves up included Israel Bitcoin Meetup gaining 11 spots 21st → 9th, Barcelona Bitcoin Community moving up 7 spots 10th → 3rd and Bitcoin Stockholm up 8 spots 25th → 17th.  Keep it up. 

The losers this month include the 4 groups mentioned above plus Silicon Valley dropping 10 spots 11th → 21st, Bitcoin San Fran 16th → 23rd and Bitcoin Munich which had debuted at #1 last month falling to #11 this month.

If you would like your meetup added to the list just ask.  Good luck to all you meetup organizers this month.  If you have any big events coming up post them below.  I also post this to /r/bitcoin
