Grammar, etc

As a sometimes grammar (and spelling) nazi - I blame my parents - I found this discussion of the so-called Oxford comma wars fascinating (so-called in reference to the Oxford University Press style guidelines). I have done a bit of editing of other people's writing and always "corrected" such phrases as "red, white, and blue" to "red, white and blue" omitting the comma before the "and". Now, I discover that there are good arguments on both sides of the debate and I have been taking the anti-Oxford comma side along with a majority of the UK and against those in the US. Here's just one example from the above-linked post:

"The highlights of his global tour include encounters with Nelson Mandela, an 800-year-old demigod and a dildo collector."
[This] supports the use of the Oxford comma, but only because it keeps Mandela from being a dildo collector. However, even the Oxford comma can't keep him from being an 800-year-old demigod.

The same source that mentioned the Oxford comma wars also linked to this post about the use of space(s) after a full stop. At some stage during my public service work career I picked up the habit or rule that one should use two spaces after a full stop at the end of a sentence. Now it seems that this habit needs to be broken. The convention was first introduced when typewriters meant that each character took up the same amount of horizontal space - called monospacing - and the use of a double space at the end of a sentence made it easier to clearly see sentence divisions in somewhat unevenly spaced characters (where, for example "i" takes up the same horizontal space as "m") and hence made the text easier to read. Nowadays, the vast majority of fonts are proportional (with the notable exception of Courier) and the use of a double space in a proportional font actually makes text harder to read.

Having done my utmost to check this post for grammar, spelling and double spaces, I will tentatively send it out into the world. Feel free to let me know of any errors that have slipped through as I just adore irony!!!
