Direct Messaging

The next thing I want to cover about Twitter is Direct Messaging.  This is a feature that allows users that are following each other to send a 140 character message that only those two individuals see.  Ok folks, it's an email.  

Here are some uses for DM that I have experienced:

• I participated in a tweetchat and someone wanted to contact me offline to discuss a new idea they had.  I DM'd them my phone number.  Obviously, I didn't want the entire Twitterverse to have my cell phone number (and sorry, you're not getting it here either).

• A friend of mine saw that I checked in on foursquare very late at night at a local hospital.  She DM'd me to see if there was anything she could do to help.

• Another friend of mine, DM'd me to make sure it was OK to feature me on their blog. Of course I said yes!

Direct Messages are short and sweet.  Not intended to be a lengthly email.  Here is one last reminder about DMs.  Both users have to be following each other or else you can't DM them. 

OK, Twitter pros.  What else should our new friends to Twitter know about DMs?
