That's really a long time. I've been here for more than 4 years. Here is the post where I celebrated it. : Celebrating 4 years on the blockchain !.
I founded as well @dcooperation more than 3 years ago. That's the community I'm building here.
Congratulations and I hope to see you here the next year as well.
Thank you! 4 years ain't bad either! :)
