18.30 GMT

I am really looking forward to the symposium tonight. Of course I am a bit nervous but I know my subject, social networks, so that makes my presentation somewhat easier to give. I am am very interested to learn from what the other speakers have to say.

I got to my hotel last night at 20.00 after arriving at Heathrow at 17.40. It took ages to get through immigration, the lines were so long. I recommend that anyone going to a London airport look into getting the IRIS clearance if your are eligible.

Wish me luck!
