I have been acquainted with people on the web that use it to avoid real life. Some people cling to their phobias, as if it's part of their persona or something. Having a board of support 24/7 that will tell a person "there, there" every time they have a fear or bad experience is no substitute for real life. I think everyone should figure out who they really are & what they are interested in, & pursue it. Take classes, get a job, join a gym, volenteer, get some hobbies, read some books, learn how to navigate in the "real world". This cyber world is not the real world. It can get like a security blanket, a comfort zone. I believe there comes a time when it is holding some of us back.
Then there are just lazy, terminal time wasters that communicate thorough nothing but forwards, tired old jokes we have all seen a hundred times, rediculous urban legends, sappy poems about non-existant dead kids, and the like. Do they really think we haven't seen this crap a million times? They sit there, letting life go by. They miss all the weather, changes of seasons, fresh air & beauty there is to enjoy. They miss the ocean in their face & the roller coaster rides & the beauty of the moonlit night.
Not to mention the "isms" Christians, anti-governmentists, athiests, anyone obsessing about a certain belief or topic & repeatedly firing off SPAM trying to convert others to their dogma. What a bore!
Everyone, get out & enjoy life to the fullest!
