Interesting term I came across! Breaking the silence of your lurking aka delurking.

Research shared by Dr. Karen E. Dill-Shackelford that says: "It turns out that such lurkers should beware. A new study says that while Facebook activity may be a sort of combination of fun and boredom for many, it predicts problems for the lurkers. We may need to look out for Facebook envy in ourselves. In a study of emotional experience on Facebook (4), researchers in Germany discovered that a lot of frustration people experience on the site comes from envy. And that envy is much more likely to happen to lurkers than to those who actively participate on Facebook. "
