> [...] users have come to expect a certain level of interactivity. They expect that if you right click on a row, you get a drop-down menu and you can delete it. They expect that you can do inline editing of an item without being redirected elsewhere. They expect that you can create a new thing on the page without reloading and redirecting.

I like that you speak in the name of "the users" who expect a certain level of interactivity, when that same level of interactivity on a page means many of these very same users won't ever see the page load fully, either because they can't be bothered to wait enough time on a slow connection, or because their browser/device simply won't do.

I see quite a clear contradiction here. And it kinda proves the point this post make about overly eagerly assuming users have a fast enough network and/or device.
