I have been following their blog since the beginning. While they improved a lot in compare to their work on previous versions, I still think they are no where close to being in the same level as the other three popular browser in terms of standard compliance.

Few things to note:

- They are cherry picking on what standards they want to implement. While other browsers have already done it.

- They are apending more time spreading PR BS against chrome and FF and how they are less secure than IE.

- They recently declared a 2 year release cycle for IE. With IE9 expected to be released in the end of 2011. Can you imagine a browser release cycle that is ~2 years? They have learned nothing from the days of IE6.
