Just a small random observation....

It's pretty easy to make a round hole; a rotating drill does it nicely. Making a square hole generally means making a round hole and then cutting it out with chisels.

It's also pretty easy to make a square peg; just cut the sides down with a knife or saw until it's the right size. Making round pegs requires a lathe, and those are heavy and not very portable.

Fitting a round peg in a round hole isn't easy. Either it's too big, and it won't go in, or it's too small and falls out, or you've spent a lot of time and care making it just right -- and then the humidity changes and it shrinks in different ways than the surrounding wood and falls out anyway.

Square pegs aren't any easier, and there's the additional problem that either the hole or the peg might be a little out of square, so even if it's the right size it might not fit well.

On the other hand, if you take a slightly-tapered square peg and put it up next to a round hole, and give it a good bop with a mallet, the corners of the peg will push into the edges of the hole -- and, because it's only interfering in a few points rather than all the way around, it will squeeze into shape and fit together tightly, and then it will hold fast and not fall out.

So, if you're putting together a barn frame with wooden pegs in holes, there's a pretty clear right way to do it. And that is, indeed, how a lot of barns were framed.

Funny about the idiom, though.

So, Amazon has recently decided that they will only carry books printed by small presses that use print-on-demand technology if they use Amazon's print-on-demand service; if the small presses continue to use the print-on-demand services that have served them well and provided good quality product for them in the past, Amazon won't carry their books.

This blog post on The World on a Slant explains why you should care.

This is a pretty big thing. Print-on-demand isn't just a vanity-press these things; a lot of reputable small presses use them, because carrying back stock is expensive when you're publishing for a niche market.
