Personal Brand - one of the things I feel least comfortable with!
A google search of my name threw up a well known (presumably!) spiritual healer and a New Zealand Librarian.  I flicked on a few pages and abandoned all hope by page 12!
Adding the town I live in at least got me on the first page thanks to an entry on my workplace library website (an old version!!)
Will I bother with Linkedin? Possibly... 
Still to be convinced.  I have, however, added my photo to my twitter account, but sorry guys - I'm basically a private kind of person :-)
