I must admit that I am one of those that complains often about the many horrible articles placed on HP that are literally unreadable.
As mentioned above, proper English is what we all desire to read.
And we all want to read an article or story that has a good flow, that entertains or educates us.
We trip over so many computer generated x-language to English conversions lately from the Far East and other sites, that are put out there with an obvious goal to "make their fortunes" from HP.
As to using regional or national inflections, slang, and such, I actually love to read those that I find where I can get a true feel for another culture.
So, Write On!
