Sorry for my slow response. I'm happy to share some data with you.
Quoted from pinster68:
I'm wondering if Robin can share if the membership (and therefore our hobby) is growing.
At the end of November, there are 24,208 "real "Pinside accounts. That's the number of activated, non-blocked/banned/frozen/dupe accounts.
Of those 24,208:
...13,330 Pinsiders logged on in the past 365 days
...5,977 Pinsiders logged on in the past 30 days (of those, 3,440 have made at least one post on the forum.)
...4,456 Pinsiders logged on in the past week (of those, 1,984 have made at least one post on the forum.)
This year we have had between 7 and 35 new signups per day (depending on the day).
Quoted from Whysnow:
I would love to see a figure of Pinsiders online trend for the past 5 years. I would love to see a unique visitor per day count figure for the past 5 years.
"Current Pinsiders online" count data was never stored anywhere, sorry.
I've included some analytics data graphs for the time period Nov 7, 2009 and Nov 30, 2014.
Note: the area marked "oops" was an analytics blackout due to an error on my end. We have no visitor stats for that time period.
