Curt Schilling, Internet-savvy Boston Red Sox pitcher, has "taken to commenting on blogs":http://www.bambinoscurse.com/archives/2004_01_04_index.php#bc107339620481233772. If you ask me, which nobody did, I'd say it's important to take his actions in our little corner of the Internet as the actions of a man who's experimenting. People express themselves on the Internet every day. First-time blog commenters make mistakes; everyone has to get used to the culture of a particular web board when they start reading it.
Curt's gonna be the same way. I don't particularly care if he's a Major League Baseball player; I'm personally inclined to cut him the same slack I'd cut anyone new to the game. Which is to say not an infinite amount, but I gotta figure he won't be perfect.
