Gartner: Take a Survey if you can

Those funny guys at Gartner sent me a link to a survey they wanted me to take. I figured it couldn't hurt, so I clicked the link. Here's what I got in Firefox:

Microsoft OLE DB Provider for ODBC Drivers error '80040e10'  
 
[Microsoft][ODBC Microsoft Access Driver] Too few parameters. Expected 1.  
 
/survey/Include/SurveyUtility_inc.asp, line 307
 

So I tried it in IE, and it worked fine. Even better - if I toggle a plugin setting so that Firefox reports itself as IE, it works fine in Firefox. So Gartner's inept web gnomes specifically look for the Agent String and die on non IE ones (with a stupid looking error message). Explain to me again why anyone takes their advice seriously?
