Future status is uncertain.
Twitter has changed their API to require SSL (Secure Sockets Layer) on -all- connections, a complex operation beyond the Arduino's ability to handle. The code is being kept around on the chance that a suitable proxy service becomes available...but at present we have no such service, no code for such, nor a schedule or even a firm commitment to pursue it.
For projects requiring Twitter we now recommend using an SSL-capable system such as Raspberry Pi. For example: https://github.com/adafruit/Python-Thermal-Printer
Gutenbird demo sketch: monitors one or more Twitter accounts for changes, displaying updates on attached thermal printer. Written by Adafruit Industries, distributed under BSD License.
Designed for the Adafruit Internet of Things printer http://www.adafruit.com/products/717 (discontinued)
REQUIRES ARDUINO IDE 1.0 OR LATER -- Back-porting is not likely to occur, as the code is deeply dependent on the Stream class, etc.
Also requires Adafruit Thermal Printer Library: https://github.com/adafruit/Adafruit-Thermal-Printer-Library and Adafruit fork of Peter Knight's Cryptosuite library for Arduino: https://github.com/adafruit/Cryptosuite
Required hardware includes an Ethernet-connected Arduino board such as the Arduino Ethernet or other Arduino-compatible board with an Arduino Ethernet Shield, plus an Adafruit Mini Thermal Receipt printer and all related power supplies and cabling.

This REQUIRES a Twitter account and some account configuration. Start at dev.twitter.com, sign in with your Twitter credentials, select "My Applications" from the avatar drop-down menu at the top right, then "Create a new application." Provide a name, description, placeholder URL and complete the captcha, after which you'll be provided a "consumer key" and "consumer secret" for your app. Select "Create access token" to also generate an "access token" and "access token secret." ALL FOUR STRINGS must be copied to the correct positions in the globals below, and configure the search string to your liking. DO NOT SHARE your keys or secrets! If you put code on Github or other public repository, replace them with dummy strings.
