My current annoyance is people who set themselves to appear offline on Skype and Instant Messengers (and especially when they later complain that no one contacts them).
When they contact me and I see their status says “XXX is offline” while they are talking to me I can feel my temper rise. It’s like having a phone that makes calls but can’t take them. The height of internet selfishness… “I can talk to anyone I want whenever I want but screw you if you want to initiate contact with me”.
Any complaints about loneliness or missing news from people who do this will be binned. With great enthusiasm I’ll add.
