Jamas.net has been my pet project for over 18 years. In all that time it has served no useful purpose to the world, other than to entertain me.
The site uses a fantastic CMS called WordPress. I now manage a total of 36 websites using WordPress. A lot of the time this site gets used to test WordPress ideas out before deploying to one of those other sites.
So take a look around and be amazed by the uselessness of it all. Then come back to be amazed time and time again!
