I was curious about Shakti after reading this and the comments, so followed the link to shakti.com on Wikipedia. It seems it now redirects to the k.nyc domain, which displays a single letter 'k'.

I wondered if I was missing something, so looked at the source, to find the following:

  <div style='font-family:monospace'>k

Nothing but that. Which is, surely, the HTML equivalent of the Whitney C style: relying on the compiler/interpreter to add anything implicit, and shaving off every element that isn't required, such as a closing tag (which, yes, only matters if you're going to want something else afterwards, I guess...). Bravo.
