With Twitter gaining a massive following and users signing up by the dozen, here are a few tips for maximizing your twitter experiance.

  Example: @meangrape I love that song too!
• D username + message
  sends a person a private message that goes to their device, and saves in their web archive.
  Example: d krissy want to pick a Jamba Juice for me while you’re there?
• WHOIS username
  retrieves the profile information for any public user on Twitter.
  Example: whois jack

  Example: get goldman
• NUDGE username
  reminds a friend to update by asking what they’re doing on your behalf.
