|Apparently, Cory Doctorow (or someone updating his entry on the Make-magazine edition Leatherman tool) forgot to close a font tag, so all the non-link text is red from that point on. It finally stops when it hits another font tag.|
For most of us personal bloggers, unclosed tags, silly typos, broken links and the like are just a minor inconvenience. They make us look sloppy, but since we have relatively few readers (who probably know us personally, to boot), they should be willing to cut us some slack.
Then again, if you don't get many readers, it's a case for not annoying the ones you get, isn't it?
However, for the folks on the high side of the long tail (to say nothing of, say, the #2 blog in the Technorati Top 100), silly little mistakes like this just make you look bad (no matter what anyone says about the blogosphere norm of "publish, then correct").
Details matter, even if you don't have a anti-site dedicated to you.
(Yes, I know I shouldn't be using a table for this.)
