I am looking for really good ideas that can either be a product or service that I can use to start a company. The ideas must be in the technology/computer category.

For example, social networking sites (Facebook, MySpace, etc), video sharing sites (YouTube, Google Video, etc), social bookmarking sites (Digg).

But the problem is, all those ideas have already been implemented and they have become very successful. I am looking for a totally new idea.

Best answer will get more than just points….

i have to do social bookmarking of my website in regular base in all top social media and social networking sites, is there any one who can do this for me in a best price also i want them to do one thing that is i want them to connect all bookmarking with one to another and make a whole wheeel of social bookmarking and social media sites?
