This is one of these ideas you only can have after a couple pints of Fosters. Australian retailer Kogan charges a tax for using IE 7 to recoup the cost to make the site work on IE 7 - Brilliant!
I have been involved in building and running web sites since the beginning. The biggest pain has been always to make the sites work on all major browsers makes and versions. These days you also need make it work on all devices. Now an Australian retailer has a great idea to push users to upgrade their browsers or else they will have to pay extra for their purchase. Kogan.com warns customers who visit their site with an IE 7 that they will be charged a Internet Explorer 7 Tax of 6.8% on their purchase. This makes the customer either go away or come back with Chrome. If you can afford to lose business, this is a brilliant idea.
The idea is so good, that now the whole internet is reporting about it and Kogan gets some major link juice infusion.
