"Using facebook is still one of the worse ways to give up your freedom. If
not yet, it will be."
"It is a stupidity to give one corporation (plus their associates, customers,
government buddies) all that personal information."
You are voluntarily giving information away. You are not forced to give
information. Same applies with identi.ca.
"But again, to each his own (the problem is programs like fb have collective
implications)."
There is a difference between a program and a service. There are collective
implications with any service you use.
