Magnitus: Well, keep in mind that in an international setting, English is not the first language of many posters.
Some people are annoyingly lazy when they type, but nobody likes a language police.
I certainly keep this in mind when making the comments I do to people. However, there are definitely ways to tell the difference between blatant apathy and unforgivable ignorance vs. someone who just doesn't know because english isn't their first, 2nd, 3rd, etc. language. This is obviously (I think) directed at the native speakers who are butchering the language and communication with their apathy. There's also an extreme difference between people who just like to "get on" people for their mis-uses (condescending) vs. people who are just fed up with the perpetuation of stupidity via the way they speak/type/communicate in general (it is bad here in the US - REALLY bad.)
