I'm simply raising privacy concerns I have and I believe it affects us all. I was disappointed this model did not address it. Invasion of privacy, profiling and tracking are big issues in my opinion and I would be curious to know why you don't think they are worth mentioning.
I do think phone calls, and spoken word in general, are highly effective. You are not helping yourself socially by refusing to speak to people who are calling you and if none of your friends or loved ones call you, there is likely a problem (I don't know your exact circumstances). I also think it's a fair claim that people are much more likely to value a hand-written letter over a chat forum message. You are offering something tangible!
I'm just proposing alternatives to socialization on a platform like FB which really is, I think, hurting natural and more effective means of communication and self presentation. I'm not saying there isn't a good place and use for internet chatting and what-not, those are great social tools too.
Just to repeat, my main point is I don't think we should have our social lives commoditized. I do not think we should be profiled and tracked across the internet. I see this ending very badly. That's all.
