I agree wholeheartedly with Abigail-II on this.   Speaking out against OT posts is the best way I know of to address a strongly potential problem *before* it becomes an actual and substantial problem.

I don't dislike OT posts out of arbitrariety, rather because they invite a trend toward slashdot-ness.   One of the things I really like about the Monastery is that interaction here is mostly reasoned, civil, and mature, which contrasts tremendously with anything-goes sites.   S/Nr++

I believe that the Monastery's fairly narrow focus plays a primary role in keeping this community a positive and enjoyable place to frequent.   Personally, I have no end of (SQL|*nix|bash|win32|hygeine)-ish questions that I'd *love* to be able to post here.   But I recognize that it would be detrimental to the community to do so.   Hence, I bite my tongue, and spit dat chat in de CB.

For any who advocate a more laissez-faire approach, I'd encourage reading through some of Clay Shirky’s Writings About the Internet.   I don't agree with everything he writes, but his commentaries on 'net communities and scaling make a lot of sense.   Here's a couple notables, there are more.

• A Group Is Its Own Worst Enemy
• Social Software and the Politics of Groups
• Communities, Audiences, and Scale

To summarize, I submit that it's better for the Monastery as a community if off topic posts are gently, firmly, persistantly, and consistantly discouraged, and done so *before* adverse affects manifest.   The CB provides a great facility for non-perlish discussions, with few-to-none adverse affects on the site.
