This is good in that it adds the ability to open third-party sites without falling back to the core browser app, but it's a bit awkward since it uses a mechanism totally different than how the browser handles it. Multiple tabs might be nicer, so that the user could switch back and forth between the original app and the site(s) they opened. I tend to use the primary browser instead of site-specific webapps because it gives me regular tab and browser functions instead of the more limited functionality in webapps.
