blogs- replacing relations or just another self expression way?

I just heard a comment that in time to come blogging would eliminate any need of having a Girl friend. Imagine the age when your read about your wife's secrets from her hidden blog. and do worry, its quite possible. its quite being theorized the advent of blogging and its consequences. learned people have openely expressed resentment about tools like these and cropping up of social networking sites, while people (like me) have found a new found way of self-expression and venting daily shit by indulging in it. Surely, they say it helps reduce one's dependence on others. can we say the old 'lovely' long conversation has just given way to short sms, scraps and self-expressing blogs??

Its common (and imperative) for people my age trying hands at wooing and getting support from the other sex. the main reasons a person needs a GF or a BF are broadly::
emotional support, sex and a being in a more powerful position with peer group.

well, blogs and social networking just help majorly in getting the 1st (though in a few cases it has helped guys getting random chicks for one nite stands, but thats rare). the other two are always achieved by 'hardwork' .. (and i mean that)
then why is blogging popular among everyone?

i believe the major reason is that in the age of networking, layers of restraint and practice prevents the ruthless, uncultured true-self of every individual. while gargantuan amounts of frustration lie in everyone's mind, this frustration only needs a vent. most people blow their minds off it on some individuals in the name of emotional support(family, close friends etc.) while rare cases throw it out whenever their thresholds become full. others are using blogs to that effect.

blogs are also a place to show a different aspect of a person (rafael nadal launched his blog recently which prompted me to write this post) or cater to the fan-base by providing deeds of heroism and motivational stories plebians enjoy. but anyways, for me its just another tool of self-expression and helps in regaining focus after writing unfocussed shit no one could ever finish understanding about.
