I can't wait for a service to pop up where for $500 they will make you an amazing, sterling Facebook account you can "share" with people. It will be populated with believable postings from other people you know, yet all of these other people will be cardboard cut-outs.
My cousin and I came up with a similar idea; we called it Fakebook, and then promptly went on to forget about it. There's gold in them there hills, though!
