Cramer is an entertainer and knows as much as you or I which, frankly, isn't all that much. However, he can get neophytes interested in investing which is a good thing. The downside is that said neophytes BELIEVE he KNOWS and will follow him blindly. I'd like to hope that their initial losses are small but they commit themselves to learn more about investing. So, I think Cramer provides somewhat of a service to the younger among us but, as you know, it take a bit of time and discipline to start making real money.
