Social Networks Boon or Bane ? Dear Friends,

I was wondering what is the purpose of signing up with so many social / professional networking sites ? There are many more but i am just listing below 15 of them. Just look at the list below :

Facebook
Toostep
Bluechip Experts
Multiply
Ibibo
Ringo
Hi5
Stumble upon
Connecture
Plaxo
Tagged
Brijj
Joso
Yaari
Mys pace
Wayn

If one were to be a member then his full time activity is to keep posting in these places only ! Will there be churn and some of them will get wound up ? Only time will tell.

How are linkedin members are managing so many a/cs and what is your advise to other members as to wht is the acceptable level of sites.

Please rank them in terms of utility and VFT (value for time)
