About 5 years ago it just started to fade.. probably as I started to click less on the new JS libraries etc, and more on the obscure interesting learnings (but also could be due to the content that makes the front page.
Every once and a while I jump on, look at a few links, read a few articles, and feel a bit disappointed that I don't have my rush anymore... I think its healthier, less addictive, but what happened to my good ol' junkie-hit days? :)
