Slashtag / Microsyntax

Slashtags or Microsyntax are a set of short community-created conventions for attributing information on Twitter. They are designed to be succinct and provide an easy way to provide metadata about a tweet, especially when "retweeting". A word like “follow” (to subscribe to someone’s Twitter feed), and the symbols @ (denoting an online name) and # (a “hashtag,” denoting a searchable topic) have specific meanings on Twitter that have begun to migrate across the entire web and beyond.
