Comparing this Blog with LinkedIn Group Discussion

How does posting to this blog differ from posting on the LinkedIn Group ASQ-0704 Discussion page? Are there reasons why one is better, or times when it is preferable to use the other? For example, is one more private? To join the LinkedIn Group, you send a arequest and the owner can turn you down. Are blogs like that, or can anybody view them?

New method of communicating for ASQ 0704 members

Just wanted to introduce another communication tool for the membership.
Hope you enjoy.
