Many people know about the annoying pop-up ads served by this site, but not many of then know that, for Mac users, one of the most frequently rotated ads here is for rogue antivirus MacKeeper. And if you don't have a dedicated ad blocker or plugin click-to-play functionality to prevent Adobe Flash from loading automatically, you could be in danger of infection even if you try to close the pop-up by clicking the red "X" button. Here is a screenshot of a MacKeeper pop-up, foiled by Chrome's plugin click-to-play functionality (pop-up is harmless as long as you don't click to run Adobe Flash Player): ***** This content comes from a third party, and the site's administration may or may not be aware of it. But either way, it's guilt by association. Do NOT visit this site without protection from Flash-based exploits!

Mixed reaction Good: Free Good: Basic information Mediocre: Comments - some helpful, some just cr*p Bad: Hard sell advertising Bad: Not thorough and minimal or vague examples

Very useful however 11 different third-parties getting your information via web bugs and the like? That's a little much for any service/site let alone a reference site of this caliber and the overall design is very, well... unprofessional for Merriam-Webster.
