I am a regular user of Yahoo IM (my ID is nostall160). Chatting online is a fascinating process, since one sees all sorts of behaviours online, ranging from the open, friendly and interesting, through to the dour, monosyllabic, rude and duplicitous.
One duplicitous behaviour that I see all-to-frequently is the habit that many people have of apparently logging off of Yahoo immediately after you have sent them a message. I say "apparently" because in all probability, they simply went Invisible because they didn't want to talk to me. I have seen this behaviour persistently from some Yahoo users. It is rather amusing, because it gives away their attitude and intentions immediately. If they wanted to not speak to me, they could set their profile to be Invisible to me, or they could set it to be Invisible to Everybody.
I have become somewhat tired of being given the brush-off and being subjected to duplicitous behaviours like the one outlined above. So, commencing immediately, I am not going to initiate any Yahoo conversations. My Yahoo will show my true status (I will not hide), but I will only respond to conversation initiations. I will not initiate any conversations. I want to see how much effort other folks are prepared to invest in communications with me. I feel that I have been investing too much effort for too little reward. Time for other folks to pick up the slack.
UPDATE - I logged onto Yahoo just now and one person appeared to logoff within seconds...classic case of somebody ducking a conversation, when I had not even tried to initiate one. This person has been doing this persistently for weeks, so I guess that they will have to talk to me in the future...
