While I couldn't give an approximation on your websites worth, I can tell you that your domain is pretty keyword rich. I Googled "Stupid Video" and got 6,220,000 results for those keywords. I'm not sure if having a .org can affect your SERPs, but I doubt it. Change the layout a bit. Maybe turn it into a Youtube like portal where people can upload stupid videos to it. Monetise it as a Youtube for stupid videos and get some PR/Alexa, the sale will be extremely high. It's got potential, hold onto it.
Nice potent domain. A high $xx domain. I agree with the above statement and you can also make a blog with stupid video (Say title: Stupid Video Org ~ The web's most stupid video collection) Add a widget that allows people to rate and comment like at Youtube. Running a Youtube site like is a bit difficult I am afraid with all the FFMEG prob and all. Stick to something simple and unique. Hopes that helps Cheerio
