Oh wow! I’ve read some blogs over this and that and the success of Discourse in the past but those are some amazing stats! 
I first encountered Discourse as a regular user around mid 2018 (which would have been around V2.0 ish) and I’ve never looked back since. So for around 6 years (definitely not as long as others) I’ve watched Discourse grow into what it is today! So I definitely I second what Lilly said above, thanks Team for the continuous development of Discourse. 
I just checked and I’m surprised I’ve been here 5 years already 
I’m still waiting for $20m to appear in my bank account one day. Can’t give up hope lol
