I have been having the same issue! The computer just ignores the scraperwiki.sqlite.save function.
Also all scraperwiki functions seem to not be working. For example:
html = scraperwiki.scrape("http://www.AnyURLYouWantToScrapeGoesHere.com)
Just scrapes the website of Columbia University's computer science department, not the URL you put in there. Which is just bizarre. Please help!
