Everyone has different judgment over karma. In my case, I treat it as same as merit. And regarding giving out karmas, I follow the same mindset I followed in the other forum. I would send out positive karmas if I like the content, and if it's about technology and stuff, they they certainly would get somethings from me. Sometimes, I would send good karmas to those who quoted me, even if the content isn't that much of a quality. I just do it as a sign of gratitude/thanks to that person. As for negative ones, I rarely send it, not that I don't see bad posts, I do. But I don't feel like giving out negative, unless the content is of total trash.
