Google just announced that it is dropping support for older browsers across a large number of their service starting August 1st. Gmail, Google Calendar, Google Talk, and Google Sites users will need to be on the latest or next-to-latest major versions of browsers, or risk not getting the full functionality of these services. The only supported browsers will be Chrome, Firefox, Safari and Explorer.
I think this is great news. Developing web sites that look good in older versions of browsers is a major pain in the butt, and anything that encourages people to upgrade gets the thumbs up from me. Looking at my stats, currently just over 10% of all visitors to one of my non-techie sites use Internet Explorer 7 and about 2.7% still use Explorer 6. Considering IE7 was released in 2006, it is ridiculous that so many people are still using IE6. Since IE7 is one of the browsers Google is dropping support for, I hope it gets people upgrading their browsers.
