Google Asks the Question

Via my feeds, a post on the Google Operating System blog that notes Google Converts Queries Into Questions:

When searching for [alcohol with the highest boiling], Google converted my query into a question: “Which alcohol has the highest boiling point?”

Me too:

alcohol_with_the_highest_boiling_-_google_search

I ran a related query – alcohol with highest boiling point – which offered a range of related questions, albeit further down the results list:

alcohol_with_highest_boiling_point_-_google_search_and_add_new_post__ouseful_info__the_blog____-_wordpress

Google results trying to draw you into a conversation – and hence running more queries (or questions…)?
