Since I don't use twitter.............
Can somebody explain to me the jokes they make to Stafford about how, "This isn't twitter"?
When you post something on twitter, you can tag particular words by putting a hash mark in front (or an at sign in front of a user name). Take a look at the official Miami Dolphins twitter feed:
http://twitter.com/MiamiDolphinsHash-tags include #FinsFriday, #godolphins, #MIAvsIND. They are converted into links and if you click on them, you get a list of other Twitter posts that include that hash tag. In effect, it's a way of grouping your post with others, making it easier to find for anyone interested in the same topic.
Putting hash tags in front of words on Facebook is completely meaningless, hence the joke.
