For the most part I'm fine with minor typos - and even find them endearing much of the time - so long as they don't crop up in excess. That little hammer dent that shows where the carpenter missed the nail with the hammer: "Oops! You're getting the next round of beers," as per some woodworking traditions. It reveals a more complicated human behind the craft.
But there are plenty of other errors that are serious enough, which change the meaning of the piece or the function of the crafted object, that require one's attention and correction.
I happened to catch one in a previous piece (already corrected), in which I typed "Baltic provinces" instead of "Balkan provinces," as part of the Roman Empire. No, the Baltics were too far north for Rome. It was the Balkan region that bred some of the really tough ruling stock.
