Blitz does help. It forces you to calculate faster, develop, and devise faster. It is a good training tool to help one be more efficient with his/her time.
Blitz develops and reinforces bad habits. IF the time that I have spent playing online blitz had been invested in reading chess books, I would be a master.
However, blitz is fun and I am an addict: http://chessskill.blogspot.com/2009/01/blitz-addiction.html
I disagree. It doens't develop bad habits unless you are a little kid and cannot have good judgement about how to play in a longer time control. As long as you aren't moving too fast in a tournament it is ok. Blitz quickens a person.
