I'm worried that the websites I'm scraping from will be updated and will no longer work When I worked for Internet Brands, they bought a site called Tjoos (a coupon/deal site) that amassed what was at the time the largest number of merchant sites using a proprietary screen scraping technology. It is a very fragile method, and a good portion of the codebase was dedicated to config classes that needed to be updated with each change to a given site. The founders had to keep hiring developers to keep up with the demands of constantly updating scraping definitions, so the site had a lot of revenue, but little profit when IB bought it. Surely by now Internet Brands has updated the site to use the same engine that powers UlitmateCoupons, BensBargains, DealLocker, etc.
