intertwingly

Mark Pilgrim: Anyone who tells you that HTML should be kept “pure” (presumably by ignoring browser makers, or ignoring authors, or both) is simply misinformed. HTML has never been pure, and all attempts to purify it have been spectacular failures, matched only by the attempts to replace it.

I strongly agree with Mark’s statement.  Furthermore, I believe that it is a useful predictor of which parts of HTML will ultimately succeed and which parts will ultimately fail.

I’ll add that Mark’s closing statement that The ones that win are the ones that ship. is correct albeit incomplete.  Shipping is necessary but not sufficient.
