Savages Golf Blog just started last month. What I like about John Savage is the premise to his blog. He “loves golf mainly because it’s the last traditional sport, and wants to keep it that way.” Amen brother.
Hireko Golf is a club manufacturer who is using blogging to help promote themselves and get news and information out in a timely manner. Their blog is here: http://hirekogolf.wordpress.com/. I like that they use the web’s best best blogging software, wordpress. But they could use their own URL instead of a subdomain of wordpress.
