By contrast, many modern Internet communities now advise newbies to lurk for some time to get a feel for the specific culture and etiquette of the community, lest they make an inappropriate or redundant comment, ask a Frequently Asked Question, or incite a flame war. This leads to the tongue-in-cheek command to "lurk moar". The verb to "de-lurk" means to start contributing actively to a community having been a lurker previously.
There are also some who lurk on a forum habitually, and rarely, if ever, contribute. It is generally difficult to guess how many such lurkers are present, due to their silence. In flame-wars, a participant who is losing an argument will sometimes claim to receive email support from lurkers. This inspired Jo Walton to write a filk on the subject entitled "The Lurkers Support Me in Email".
With the advent of social networking sites such as Myspace, Facebook, and IMVU, lurking has been expanded to include visitors from one "homepage" to another. This lurking typically involves reading personal information about another user, looking at the user's pictures if available, and may also include leaving a message that simply states "I'm just here lurking."
