se your Connections

Having a apres work pint today, I got into a conversation with John about utilising network connections for the greater good (ie: own own) and how online facilities such as Linkedin and Facebook (in my view, a middle-aged MySpace) are the natural extension of the kind of networking that we all do daily. Or not.
Now I'm a dabbler in Linkedin, and to feel the benefit you really need to spend time and effort in schmoozing, tailoring your CV etc. I've spent time on neither, and to be honest, apart from word-of-mouth tales and Marketing spin, I've heard no stunning tales of success. John takes it one stage further and maintains that he enjoys a certain an anonymity with regards his career furtherance. Ironic bearing in mind he was bemoaning my lack of activity on the Blog front and has had a spurt of posting lately (he's a great writer and is completely wasted trying to convince Corporate Europe that online services from a certain Info-aggregator are worth buying into).
I have promised that I'll send him an invite to Linkedin so he can start widening his horizons and possibly garner some interest from someone who is looking for the right mix of Frustrated-Muso meets Cautious-Aggressive Business promoter cum online evangelist. Which brings me to the point of my post....can anyone remind me of my Linkedin login? I thought it was the same as my Plazer/Flickr/Last.fm/twitter/myspace/facebook login, but apparently not....
