25 apps of christmas–facebook, twitter and linkedin
first it was myspace, but then as soon as facebook allowed microsoft employees to create profiles, i jumped ship. facebook quickly became the main personal/social connection for me (surpassing email in most cases). now twitter along with facebook are both important ways to stay connected with my friends and colleagues. linked in has always been more business than social, but these three applications have kept me busy on various platforms in 2010.
