Just as I announced, I have randomly picked up one of the (couple of) tweets opting to win the copy of HTML5 FOR WEB DESIGNERS
I could have used a coin but for rules sake I used the stated method:

So the fisrt of the tweets was the winner, and this was: @Wepwawet’s
UPDATE: Look at the face of the happy winner!

There will be a second prize of a Friendly Neighbourly Beer for all the other participants (namely: @supersonik86) you will be contacted about this :D
