Sometimes, rather than some "simple" grammar mistake, blog posts are just wrong. Take, for example this Kotaku post about the upcoming Champions Online open beta:

The open beta will commence next Monday, August 17, and will run 24/7 until it closes.

The only problem with that statement is that next Monday isn't August 17th. By my watch, today is July 9th, so August 17th is more than a month away. Check your facts, people!

Update: The article has been corrected to remove the "next Monday" descriptor.
