Facebook Conundrum

In the last week, I've gotten about a dozen "Facebook" add emails, from people I've known for many years. Thing is, I have no Facebook page. Dr.Desert Flower does. Our son does. His lost cat Dylan even has a Catbook page. So I am faced with the conundrum: do I ignore all those invites or embrace the whole FB concept, and try to adapt to the whole "throw a sheep", "wall posting", online networking stuff? I am sure those who have already enthusiastically embraced FB would encourage, counsel, and cajole me into the latter. Many others who have not signed up would likely, inertially, apathetically remain mute. I dunna know.
