I never got around to grinding enough karma points on there so that the platform will let me actually engage with it. Since I can't post answers or even vote on things, there's not a lot of reason for me to bother logging in. As a result I just mooch off what I find and leave.
I can't be the only one. Their walled garden kept me out.
I stumbled on an obscure question years ago on one of the sub exchange sites that dovetailed precisely with something I'd been working on for years. All the proposed answers were subpar so it was like I was born for this particular question. After cracking my knuckles and preparing to reply I realized I couldn't. I didn't have enough karma or whatever. And that was the end of that.
Same for me. I have an account with zero karma on it. When I created it I was a total programming novice fresh out of uni and could not really contribute. As time went on, I could definitely have started contributing, but not having any karma became too high a barrier of entry - I'm using it during my work hours, I can't just spend endless time grinding.
