@jakenybo Web scraping is closely related to web technology, as it involves extracting data from websites and web pages. You can place your new section on Web Scraping under "Web Technology".

@shhossain, i just put quite a few hours in today working on the new Web Scraping section. i created an overview document of Web Scraping and i am now working on a simple Web Scraping example. i will be going out of town later this week, but i hope to get this issue pushed up for review sometime next week if all goes well
