Apologies to those of you who have been trying to add comments and were prompted to register (which in turn was turned off!).

I had never intended to turn on the registration requirement and I am still puzzled about when I mistakenly made that change.

I have changed the configuration and you should be able to add comments again without having to register or enter any private information.

Safari 4 is out of beta and was pushed out to Mac OS X users via Software Update today. Two things I noticed: the tabs on top are gone, which is unfortunate. Second, there is a clear indicator in the address bar for when the browser is loading a page, and interestingly, this seems to be used even for AJAX/XmlHTTPRequest transfers. That’s a nice feature.
