"If you think that the shared armrests are for whoever first claims them — a rule that frequently would leave the middle-seater wedged between two elbowy people — you have entitlement issues."
#8 on a list of 12 rules for airports and airplanes.
And this post is following a rule for blogging that I just noticed: If you find something to blog about via a blog that deserves a "via" (or "hat tip") link, you can better fulfill your obligation by finding something else on the hat-tippable blog and doing a separate post about that. This post represents the something else, and the next post will be the thing I found via this blog, and I'm not going to put a "via" link on the next post.
The idea is that the blog I'm linking to here will get far more click-through readers from this post than from a "via" link that telegraphs its obligatory quality. I'm going to follow this rule in the future — and by the way, I think Instapundit follows it — but I'm not going to keep pointing out that I follow it. And I won't follow it unless I genuinely would have chosen to blog the something else, in accordance with the longstanding Althouse Principles of the Bloggable.
