(This post was originally written for theYahoo! Developer Network blogand was published there on October 5th; it's duplicated here for posterity.)You're stuck in a room on the first floor of a venue with no natural light, people keep expressing surprise that you're there, there's a bizarre voucher system operating for getting a cup of coffee and the free public wifi is holding up far better than the venue's net connectivity which is buckling under the strain of multiple laptops, iPhones and Androids.It can only be a tech conference; this one is in London and it's called FOWA, or the Future of Web Applications to give it its full name and it was held in the rather grand sounding Kensington and Chelsea Town Hall, near High Street Kensington tube station.There's a booth with some strangely comfortable sofas and chairs, a purple orchid, loads of purple swag, "geoballs" and a free wifi point called yahooligans.
