While you might think this is narcissistic [it is], it also has several practical uses. If you post what family/individual you are currently researching, other users searching for that same name can find you and make contact. If you “follow” (Twitter for subscribing to another user’s updates) your favorite applications, you’ll know when they have a new update available. I’m also beginning to see local news organizations posting headlines, weather and traffic updates. Along that line, it’s also a good way for family members - both local and distant - to keep up with each other.
