But every once in a while a really nice juicy argument comes along and makes it all worth the while :)
Missed calls
Missed Calls were (are?) a big part of the Indian (youth) culture when I was going through college. Cellphones were getting cheap enough for college kids to carry one, but call rates were not cheap in any sense of the word. In that situation missed calls were a legitimate form of communication.- Giving missed calls to the "wealthy" party so they could call back and bear the cost of the call. This worked well with parents :D and sometimes with wealthy / generous friends.
- Giving missed calls to indicate yes / no (one ring = yes, two = no). Useful in all manners of covert transactions including flirting with guys / girls from orthodox families that WOULD NOT allow calls from friends of the opposite sex. err... yes this is true.
- Giving missed calls to indicate "I'm here". When you were meeting a friend and expected him/her to come down / out of the house so you can get going, you don't go to the house. That's weird; a waste of time; a thing to avoid at all costs (exchanging pleasantaries with the friend's family, having a bit of snack / tea offered to you, sharing awkward silence with your friend's super cute sibling, etc). So you give a missed call meaning "Waiting downstairs. Let's go."
A question of ethics!?
Apparently the US is new to all this. No one in the US gives missed calls. People just talk. How boring. But when this subject came up couple of weeks back in the TW NY Office, one of the arguments presented was around ethics!! The argument was something like this...Although the missed call is free to you, the telecom company incurs cost to connect the call and so it is unethical to use missed calls to communicate because you are not paying the telephone company!!My very first reaction was, of course, "That's a ridiculous argument!!". After thinking about it long and hard I my reaction changed to "It really is a ridiculous argument!!". I vehemently believe that missed calls are legitimate and you are a fool not to use them. You are totally within your rights & not doing anything illegal. Its the contract that the phone company signed up for and so if you can legitimately use the exploit in the system. I consider is "Fair Use". (listen to that regardless; its a masterpiece)
Its not like the phone companies don't know about this. They can't do anything because of a deadlock in a competitive market. If one of them starts monetizing missed calls the others will eat it alive and gain significant market shares.
The catch
There is however a roadblock I faced while making this argument. I was looking for other examples of this behavior (using the free part of a service to gain benefit) and I couldn't find a single one! I know its impossible but you have to help me out here. Missed calls are at stake! Is this really the last legitimate exploit that we have on out hands? Are we so boring? Say its not true...UPDATE: A friend pointed me to this episode of "This American Life" that explores the question of loopholes and ethics at a much deeper level than missed calls.
