Oh no! Mark Cuban has too many friends on Facebook. The graceful Web tycoon just bumped his head against Facebook's 5,000-friend limit. Now Cuban faces the daunting challenge of deciding who among the 100 friend requests a day he should honor. Of course he blogged about it.

Could this person really be my friend? Could this person really be someone i do business with ? Did I actually know this person? To any of you who I have deleted or ignored. Its nothing personal

On reaching the summit, Cuban writes, "It was a weird moment, but actually one that I have come to respect and appreciate." I'm sure only Sir Edmund Hillary can relate, Mark. Or, maybe Robert Scoble.
