You may have read my post the other day regarding various companies ringing or emailing on a near constant basis to try and get us to do things we either already do or don't want to do. Chief amongst these was Yell.com whose system (which did sound pretty good) appeared to base it's success rate upon its visibility to Google in a particular keyword or phrase. The thing with it was not only that it was expensive (from memory I think their offer period - as if the prices ever change - listed the prices in a £50 per month and upward category) but also I'm sure we could do this ourselves anyway.
I have noticed a worrying advertising trend here in Luton which I presume is happening everywhere - the rise and rise of the human advertisement also known as 'the moving billboard'. On my way to the gym on Saturday there were literally tens of poor, bedraggled looking lonely fellows shivering in the cold holding aloft a desperate looking sign advertising some generic offer or other, which you would have already seen in countless other locations, including 'tinterweb, TV, radio and newspaper. The ones I saw were positioned in some of THE most random places in the town and were in each case advertising on behalf of Dominos Pizza.
