Below is the browser market share for April 2010, based on traffic to my top site:
Google Chrome: 12.13%
In April 2010, Google Chrome gained 0.84%, the seventh month in a row where it gained at least 0.6%! The gain came at the expense of pretty much everyone else, with IE suffering the most decline at -0.51%.
At the current rate, IE and Firefox will be neck-to-neck by the end of 2012, with Google Chrome very close behind. By the end of 2013, Google Chrome will be #1, with Firefox #2, and IE #3. If Microsoft wants to stop its slide in the browser market, IE9 will need to be a monster hit with the users.
