Linked-In, Facebook, Plaxo Pulse, .. What to do ?

Yes, what to do ? I'm linked to Linked-In, my face is on Facebook, I've Plaxo-ed in the past and I keep getting invites from all three networks. I have come to a point that I questing the relevance for myself to maintain my network in 3 different area's. For now I've decided no to "opt-in" for Plaxo Pulse, so apologies for people who have invited me in there. You're welcome to add me via Linked-In or Facebook.
