Show HN: my weekend project - Scrapious, to export bookmarks from Delicious

It's a webapp; it could be in the form of a simple website. But it scrapes with Ajax, and you can't do that from an ordinary website (same-origin policy).

HTML5 should let the app ask for permissions, but this is seldom supported.

It would be possible to scrape from a server, but that would expose the same IP over and over again, which would be very easy for the target to block; a client-side scraping tool is run from many IPs, making detection and blocking a lot harder (I hope).

Finally, while coding the core of the app is enjoyable, cross-testing css rendering differences is a big pain. Publishing this as a Chrome webapp is a way to make sure every user (all three of them) uses the same browser.
