I've written a post about the new Ask.com and some of the features they have been touting. I compare two specific ones to Google: The searching of "concepts" (aka related queries) and the answering of questions. I only use a few searches as an example, but it's meant to be more for discussing than saying one is better than the other.

Let me know what you think of the article:
