Who the f*** decided that sentences on the Internet shall no longer be formatted with two spaces after a period?!
This is a signature from slashdot. But it is true, and I'll tell you all the little things that this statement means to me. It's more than meets the eye.
Yes, the internet is powerful, everywhere, tempting, all encompassing, and defining. What happens on the internet, whether it be 1337 speak, punctuation, or humor (itsatrap!) tends to latch on to us, because it represents the most democratic medium - everyone's voice is there, and the conscience tends to fall toward the center of the bell curve of the participants, hence, society.
The lack of a second space after the period may be the future, and, like the comment says, it might be just one guy who decided when writing html standards. That is the power, and social leveller of the web.
Any english teacher will tell you that the language is constantly evolving. Merriam webster doesn't decide what new words are available. And, the increasing rate of change of things like this on the web are really telling. Who would have thought?
