I was trying to make a list top topics being followed by followers by top writers in a year by quora. I was doing this analysis for fun. There were many interesting findings in the meanwhile : For ex: Quora refreshes its page after 53 seconds. The XML-http request is made by a js file consisting of 17k+ chars(minified form). The problem faced during this task was that the list of followers is generated dynamically(you need to scroll down the page to get more followers). I had to programmatically control this. The request being made is really unsafe(http request is being made,not https!!).
