Here's a little known fact:
Twitter and
Facebook are erupting in
popularity. Both social networks have taken the underground and
mainstream worlds by storm, and everyone from your next door neighbor
to your favorite celebrity is likely within reach. This new world of
information can be extremely beneficial; having real-time updates to
breaking news, concert listings, sports scores, weather alerts, etc.
enable all of our lives to be easier.
But as with anything, good devices can typically be exploited and used
for ill. Stories have begun to surface that highlight the risk in
disclosing all sorts of typically private information on open social
networks. Experts have spotted that both Twitter and Facebook foster a
false sense of security, as if those following you are all trustworthy
and harmless. A study found that 13% of Facebook users and an
astounding 92% of Twitter users simply allow anyone who requests access
to them have it. Through experience, we can say that protecting one's
Facebook profile seems easier, as Twitter users have to manually lock
their account in order to prevent others from following their tweets.
And even still, if a friend re-tweets something from you and broadcasts
it out to the open world, your "inside" tweet has suddenly be opened up
for everyone on the outside to see.

Obviously, letting just anyone view tweets and status updates can have
serious consequences. In most cases, blurbs emitted on Twitter and
Facebook are harmless, but by mentioning vacation plans, upcoming
business trips or meet-ups with certain people, you're also giving away
your location, time away and potential rivals. To criminals, these
minor details can be assembled in order to dig up details and uncover
secrets. If someone knows exactly when you'll be gone, your home is
wide open to being broken into. If someone knows who you're meeting
with on business, they could uncover your employer and/or location.
It's tough to think about, but it's something that should definitely be
considered by Facebook and Twitter users, particularly those who let
just anyone follow their digital lives.

Another security threat that has just recently been tackled is the use
of out-of-office replies. These messages are sent out as soon as anyone
(anyone!) emails you, giving potential enemies information on how long
you're away and who you recommend contacting while you're out. Needless
to say, these details coupled with Facebook/Twitter snippets could let
out way more information than you ever intended to be loosed. In saying
all of this, we'll just recommend that you only allow friends to follow
you on Facebook, and if you must keep your Twitter account public for
all to see, be extremely careful what you post. Anything related to
location, absence or work could come back to bite you if the wrong
people get their hands on the information.
