I'd point out that I can earn a referral fee for folks that sign up here because I pointed them to it, but don't want to appear to be doing this for money. I just found it fun, and thought that there's so many smart people on Steemit that a lot of ya'll might be interested too.
Almost every group I participated in invented multiple things in the course of our deliberations, and usually consisted of folks from at least three continents. Like I said, it was lots of fun =)
There seems to be a particular interest presently in Python programmers, so if that's a skillset you're wanting to use more, this might be a good thing to look at.
