Update: Patrick resolves the mystery as to our connection, it was through Project VRM.
I'm always impressed by the 'You may also know ...' feature of social networks - it seems a bit spooky how they can guess who else I might have a connection to (yes, even trivially simple algorythms can create spookiness).
The capture below is from Plaxo.
Of the 9 suggestions, 8 could be considered relevant - I either do indeed know the individual, or might want to pretend to (were I not already connected with them multiple times over in other networks).
But my pending friend Patrick had me stumped. A Google search didn't clarify.
Then I found him on Linked In.
And I do indeed feel a connection - just the other day I was explaining to my kids that 'Buying or selling is at the end of a transformation process which converts subtle experiences into tangible and physical ones'. That is freaky.
