Which tool was used to create this web site?

Please see
http://anmolmehta.com/blog/2008/02/28/best-yoga-exercise-video/

It is a blog. That web site contains a large number of such blog posts. As you can see, it contains formatted text, links, pictures, embedded videos.

My question is-
What tool/utility do you think was used or can be used to create such a web site? Is it simply wordpress?
Please give as much detail as you can. Thank you.
