Well, there are many cons mentioned for using subdomain on other blog posts around the internet. I've tried it, and
I'm giving it a no-go.
Why? When using subdomain and you have different CMS like we have - Joomla and want to use Wordpress for blogging
you can't use relative URLs in your CMS themes !!!
So, if you have images on: extrawatch.com/img/myimage1.png then when using the same image in wordpress theme, you'd have to use full URL: http://www.extrawatch.com/img/myimage1.png Cause using a relative one: /img/myimage1.png would make the browser think that he has to search for http://blog.extrawatch.com/img/myimage1.png That's it. Maybe this post will help other people making the right decision. Feel free to comment what do you think. Image by Paul Downey
