<p>Every new command is wrapped in a tweet and posted
to <a href="http://twitter.com">Twitter</a>. Following the stream is a great way of staying abreast of the latest commands. For the more discerning,
there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.</p>
