I'm getting totally wrapped up it.
I'm just following it on channel 4 (UK) and just seen episode 3 of season 2. I rang the number on the fake TV ad for the Hanso Foundation during the show (several times to hear all the various stuff) and had a good look around the hanso foundation site (just spent the last 2 hours looking around and following the clues) and it's got me hooked trying to figure stuff out.
I'm surprised noone else has posted about it (or maybe I've just overlooked it).
I've not been this interested in a TV show in ages and the way they have all the sites set up for the airline company etc is really good, quite engrossing.
PS if you're well ahead and seen it already, please don't spoil it for me. Just wanted to share my interest and discuss what's been revealed so far (in UK).
