Search Engine Friendly URLs

For awhile, I have thought that its better to present your website to the internet (search engines) with url’s that are search friendly. What I mean here is, instead of having a url like http://www.domain.com/cat?=1294584854, which frankly doesnt mean anything to a search engine based on the URL, it would be much more beneficial to use a URL like http://www.domain.com/the-reason-for-search-engine-friendly-urls.html. Not only is it easier for your users to remember/understand but your url is chock full of keywords and we all know how important keywords are. Today, I actually stumbled across an article to back up this thought, you can read it here.
