I am very protective about my online identity, so much so I use a pseudonym (as in this post) when I make my observations on policies, products and services.

When LinkedIn added photos, my initial thought was ‘Gee, just like MySpace and Facebook’. Now I see Twitter hooks.

When does a serious, employment-related social networking service end and another time-suck service (ala Facebook, Twitter) begin? I am not suggesting that LinkedIn has reached that point yet, but every time there’s a new hook like this, it moves closer.

This much I know: the day one of my LI contacts ‘pokes’ me will be my last on LI.
