I found the text below in a Monster.com job posting...I like the honesty in stating "Screen Scraping" is a required skill. I haven't seen any certification tests or books on it. Maybe there is an untapped training/authoring niche to fill in Screen Scraping™?
Minimum of 2 years experience in Microsoft .NET; Microsoft SQL Server 2000/2005. Preferred experience includes 5 years C# experience, 5 years SQL Server 2000/2005; exposure to Screen Scraping, SQL2008.
Please don't screen scrape my feed; subscribe to the RSS/ATOM feed instead! :)
