Bulbanews talk:Manual of style
I think we could do without some parts of news style. The month-abbreviating and non-serial-comma practice is a space-saving measure, and completely unjustified otherwise (especially the latter - a comma could not possibly be more than a third of an em!). We do not have the limitations of paper. [Though, visual economy is important with sidebars like infoboxes.]
Personally, I feel that 10, 11 and 12 should also be spelt out for the same reasons that 1 - 9 are: they are single, atomic words in modern English.
As for the quotation-punctuation usage, it's distinctly Americanist to always without fail include punctuation inside quotes. British usage is far more sensible, taking into account context, and is increasingly popular for at least quoting URLs and computer input: wp:Quotation marks#Punctuation - 振霖T 02:41, 16 September 2005 (CDT)
