Learning always takes some time, right? You've been here for 2 years , while I've registered just 18 days ago (started posting on HN about a week ago). I was a bit obsessed with karma accumulation, at the same time I was learning the community. Reading a lot daily I often find interesting articles or news, that I'd like to share with others. Don't blame me for my passion, I've already realized myself being overposting. However that has helped me to figured out fast what's interesting for people here. I'd say that was my small marketing research which gave me quick results. So now I want to step back a while, as you've said.
