Good idea for a startup.... buuut it might be better if their site worked.
I tried to register and:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) +159
System.Web.UI.Control.ValidateEvent(String uniqueID, String eventArgument) +108
System.Web.UI.WebControls.DropDownList.LoadPostData(String postDataKey, NameValueCollection postCollection) +55
System.Web.UI.WebControls.DropDownList.System.Web.UI.IPostBackDataHandler.LoadPostData(String postDataKey, NameValueCollection postCollection) +11
System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +353
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1194
Yup. Same error for me as well--it was started by a non-hacker... :) However, just quickly glancing the article, I thought that it was a very useful idea. Back in the college app days, I would scour rankings, reports, guides and would get annoyed that they'd show only a peek. Also, it wasn't super clear how something like U.S. News Report graded the colleges.
Nope, that's a misconfigured server, an error that only crops up when using multiple server without having sync'd some keys in the machine.config properly.
I got the same error on a few pages, but the site also (repeatedly and reproducibly) crashed my browser when I tried searching for a college.
I thought I would love the site after reading the article, but the actual execution kind of sucks...not just because of the programming errors, but because of the general site design and 'flow.'
