Internet Explorer 6 users are not going to be happy about this news, but it has been a long time coming. There has been a growing collection of people saying that IE6 is holding the web back, and it seems that Google has had enough of it. Microsoft does not mind, but prefers you IE6 users upgrade to their latest version instead of jumping ship. I jumped ship a long time ago; and you can use this Massive List of Web Browsers as a launching point to discover if you will as well. Either way, it is time to dump IE6 if you are still using it.
"Many other companies have already stopped supporting older browsers like Internet Explorer 6.0 as well as browsers that are not supported by their own manufacturers. We’re also going to begin phasing out our support, starting with Google Docs and Google Sites. As a result you may find that from March 1 key functionality within these products -- as well as new Docs and Sites features -- won’t work properly in older browsers."
