I think yes, twitter is dead. After a week of work i started getting 500 unique visitors just from twitter which was great. But when i checked out my earnings it was $0 As i can see twitter has been saturated by spammers. I guess the visitors are the other spammers. The Big Players are the only one's who are making a killing from it like DELL. I heard they made $11 million just from twitter marketing. I guess It's time for me to open my own company now. But, its true that twitter has finally gone dead. You can make some cents out of it but not some big checks.
