This is where STEMGeeks differs. It is more accepting of amateur content. Hack your blowdryer into a freeze gun, that's awesome let's see it.
Setup a Raspberry Pi to block ads, that's cool too.
You don't have to be going for a noble peace prize. Although that's more than welcome as well.
Even if you just want to talk about some new gadget you got, it's welcome as well. The more geeky the better.
And I think that will encourage a TON more STEM content, including stuff that SteemSTEM will curate. They might have to actually expand. :P I think people won't be as afraid that they'll spend a bunch of effort on something that won't be acknowledged for the effort.
