Mark Cuban has bought a 6.3 percent stake in meta-search engine Mamma.com...

“I like companies that generate cash,” Cuban said in this story. “This company doesn’t have to be the next Google or Yahoo!. Heck, they don’t even have to be a top 10 search engine. What drew me to them was a search for pictures I was doing for a project. It did a better job than the bigger engines. So I continued to use it.
