We are so tech savvy still we use the primitive methods of telling people the URLs of a site. This is particularly bad in podcast. Why do we tech savvy people still need to be told to put www. every time we are given a URL So from now on I abolish the words www. and .com. So if you want give out an URL just give them the search term that makes your site come up first on Google.com. So no more www. and .com just the name
Example: gizmodo for www.gizmodo.com
If you search gizmodo in Google you will get the above given URL as the first links.
Imagine all the millions of seconds of our lives we could save with not saying www. and .com everytime we give our an URL.

… and what do you do when there is one name and your choice of .com, .net, .org, .co.uk, .it, .fr, etc????DUH!
As i mentioned it only works if you have .com site and if you are popular. And most of the site that do podcast and or get ads are big so you can get to them through google.com
