> As for offline, yeah, my Internet web page doesn't work offline.
That's really too bad honestly. What about your users who want to use your site when they're offline? Sympathy with those users is why I made sure that my site works well when offline.
Whether this is actually beneficial (let alone possible) depends heavily on the type of site.
Web apps that are valuable to use offline also tend to be the kind that really do warrant client-side logic and rendering (a spreadsheet web app is a classic example).
If the site's focus is providing information (e.g. Wikipedia), then working offline really just means loading all the backing data into the browser, which quickly becomes impossible.
I'm sure there are cases where offline availability is a huge plus (your site might be a good example), I just don't think it's universally applicable.
