Zero.
This appraisal is for the domain only. I did not visit the website as it may impact my objectivity in regards to the domain. The most glaring issue with this domain is the fact that it's a .INFO. This TLD should be avoided if you have a desire to build a valuable portfolio of domain assets.
I think the name itself is good, so if you could possibly get this in the .COM version you would be in better shape. You would even have some modest value if you could lose the "my".
See below:
JOKES.COM = Great
MYJOKES.COM = Very Good < Recommended
JOKES.INFO = Good
MYJOKES.INFO - Terrible
My advice would be to blow this out in the marketplace and/or Ebay and hope for mid $xx. Then avoid .INFO in the future, BUY a good .COM, and build out a site you can sell for high $x,xxx.
Good luck!
