Oh boy. What a mess.
So there ARE two sides here.
Side 1 is the "I want to have a startup so that I can do something important to me.
Side 2 is the "I want to have a startup so that I can do something important to others. I will find some way to make this important to me as I go along.
Side 1 folks are tweaking on a moral crusade. Let's change the freaking world, folks!
Side 2 folks are deeply ignorant. I do not know what people want that I can make. Maybe they want better restaurant recommendations based on blood type. Maybe they want job recommendations. Maybe somebody would want jobs for cats. Has anybody done that? Beats me.
If this were a war to improve the future of humanity, Side 1 folks are always the ones charging up the beach on D-Day. Rally after me, men! The cause is just and victory awaits!
Side 2 folks are always trying to find a better way to make the machine gun fit to the machine gun mount. You know, if the bearing fit this other way, machine gunners would have a bigger field of fire....
Side 1 guys are the evangelists. Side 2 guys are the plodders, plodding along. Tinkering.
There is no right or wrong answer here. One out of every 10K or so of the change-the-world guys actually change the world. Very cool! One out of 100 or so of the better machine gun mount guys actually do something that somebody, somewhere finds useful. Very cool!
My problem is when the Side 1 guys go on these long tears about what the rest of us "should" be doing. Dude. I've been working and living in the startup scene for a long time. Am I supposed to get all emotionally fired up because of social injustice? Or perhaps just go do something other folks might find useful? Because that thing where you run on passion for a year and burn out? That's not so much fun.
I love charities. I love hobbies. I think it's fine to have something that's a cross between a hobby and a charity. Perhaps this is what the side 1 guys really want for the rest of us and they are just doing a bad job of explaining it. Or perhaps they should just leave the rest of us alone while we go try to make something useful to somebody, anybody.
