Welcome to another outpost of the small web.  I have been a proponent of this movement for a long time, and It brings a smile to my face being able to use something like Hey World.

I have always been a fan of Basecamp, as a product and company. Been using Hey since the beta, and also moved my company's email to Hey for Work months ago. I still use other email interfaces from time to time, but every time I do that, I miss Hey. 

I don't think I can go back to the old ways, and I'm happy with that.
