As you’ve probably noticed, Zarino and the team recently upgraded all of your scraper pages to have a lovely new, more useful look. So we’re rolling out a new set of introductory screencasts going through our new look site and giving you a bit of a flavour of the many things you can do on ScraperWiki.

I’ve started with a three minute whirlwind tour. Just an example of some of the things you can do. We’ll be adding all the screencasts to the documentation. It’s all for you so if you like what we’re doing spread the word (i.e this video!).

The next one is a SQL Query View which looks at the data with a journalistic eye in ScraperWiki. This is the second part of the tutorial where you look into a datastore using the SQL language and find out which are the top 10 publications receiving complaints from the Press Complaints Commission and also who are the top 10 making the complaints:
