Does nobody check their copy [on the Internet]?

An article I was reading last night was written by Paul O’Sullivan. Quite a good and interesting article. But at the end of the article, it was apparently written by Pau O’Sullivan.

Post and then read?
Post and get complaints?

Even my spell checker thinks that ‘Pau’ is a mistake. So how come it got out there?

Mind you it seems that society in general does not check before publishing/televising or patching. [eh Microsoft?]

Windwoes 10 updates on some machines ‘bricks’ the machine. See the Register.

But [don’t] wait there is more…
