how much is too much?

what social networking has done is make acquaintances, 'friends'. 

so how many is too many? when does a person cross that line where even their facebook account is full of 'spam' 

i put the number at a vague 100-125. and if you're really honest with yourself i think the more realistic number would be 75-80. but maybe thats just me. 

could there be a direct link between the number of friends and how insecure you are?
