The First Comment syndrome is a strange phenomena.
A group of your community strive to post the first comment to a blog or news
post. They see a post, write "First comment!"
and post. This is usually followed by two more "First comments!" within
20 seconds.
What do you do when a small group of people want to post the first comment,
and the rest find it irritating?
First, take it as a compliment. You're clearly doing a great job if people
are eager to post the first comment.
Second, pick the common offenders and let them lay down some ground rules.
The first comment must appear within 5 minutes or not at all. It must be a
minimum of 3 sentences about the news story, and you get a bonus point if people
reply to your comment…
That's a start.
