I absolutely agree with your statement. I've been reading and 'lurking' for about 3 years before I figured I wanted to start upvoting, save posts and maybe post some things. I just haven't gotten my ass around my head and done it yet... So when a friend of mine invited me to keybase and told me to link my accounts I thought I would do so. Only problem is that I couldn't do so since I have no karma.
I hope that is a fair enough explanation, but I would love to elaborate more when I'm done at work!
