This is one of those times when I *really* wish that the application developer community was more active on this list. I absolutely understand Linus' point of view, but I also feel like we are really hamstringing applications when we make choices like this and I wish that those developers were more vocally represented in these types of discussions. Going down this path would basically kill the ability to have offline web applications, because there would be no guarantees that the data would persist until the user comes back online. But since that point's already been made several times, I guess it's not a compelling argument. -atw On Wed, Aug 26, 2009 at 8:23 PM, Linus Upson <linus at google.com> wrote: > I simply want clicking on links to be safe.
