Social Media Overkill?

Almost everyone today has a facebook and twitter account as part of the SEO strategy. Its the thing to do. We all know its part of "Social Media". But let me ask you a crazy question. Do you think anyone really has time to join everyone's facebook or twitter account. At what point do we say enough? There has to be a breaking point in which its just not a good marketing point anymore. Did you ever hear the saying "if everything is an emergency, than nothing is". Do I really need the facebook link of every person I interact or do business with? Am I collecting everyone's business card? Do I need the tweets of the 100 businesses that I do business with? I guess until I can answer that question we still need to make it a part of our overall internet strategy.
