Because it reduces the chances of you happening upon someone who owns both the 
entry and the exit node on your circuit. If someone owns both they can 
perform a bit of timing analysis and figure out who you are and where you're 

See this thread

for what can happen if the same guy owns all three nodes.

Just another layer of encryption. They can't 'read your traffic'.
