Not scraping (but drowning) - London Bus Checker
Great story - and three cheers to TfL for opening up the data, something a lot of publically funded companies would do well to imitate. They still seem to be taking the site/API down a lot for "maintenance" but it's so new that you'd expect teething problems.
Just to say that not all apps screen-scrape: for example, my iPhone app London Bus Checker (plug alert, currently #1 travel app in App Store) uses the same API as TfL's own mobile and web apps. In fact, it was El Reg's very own story on the bus countdown site that prompted me to write it in the first place! www.buschecker.com for those interested.
Secondly, for those apps that do screen scrape, is it really "not allowed"? I checked the TfL Terms and Conditions, and they specifically exclude certain areas of their website from screen scraping, but the bus arrivals site is not one of those areas.
