Today's social networking implementations (Facebook, Chats clients, LinkedIn) consider an individual user included into a huge community, linked trough "Contacts". While in the real life is so different. I'm a member of family community, I belong to a friends community, I relate with my coworkers community and probably people from one sub community are not in contact with people from other sub community...or at least, that's no my concern.
"On Monday morning, a friend of mine insists to chat me about a nice girl he met during weekend. I prefer to set my status as busy. Same time a customer is thinking of buying 5000 units of my products...but as he is seeing me busy, he doesn't bother me...."
So, why to place all my contacts in a huge contacts bag??
First of all we could sort our contact list by groups...nothing new ...yet Then, we could manage statuses by group. In that way, during my working hours I can set my status as "busy" to my family & friends but as "available" to my coworkers, or during my holidays as "available" to my friends and as "off line" for my boss ;-)
With the applying of that scheduler, my aunt will not disturb for ask whether making the cheese cake or not, while I'm close to treat a profitable contract with my customers !! Similar improvement could be extended to Avatars and Personal Messages...
As we can see, this is a useful idea with no major effort to implement, so, please, Nimbuzz, Skype, Gadu-Gadu, MSN, eBuddy, Empathy, Gtalk, Kopete, Meebo, Pidgin...someone, hurry up!!! as a simple user is what I need !!! Thanks!
