will you help me understand twitter?

twitter

I Need Some Help:   For the past 6 months I have been trying to understand twitter.  And I am sad to say that I feel like I have fallen off the back of a cruise ship and am being left behind.  It is apparent to me that twitter is becoming, or already is, the new medium for social networking and communication, but I don't get it.  Would you be willing to take 5 minutes out of your day and help me understand how you use twitter?  How you use it for ministry?  How you use #'s and @'s?  Can you make a case for why I need to swim hard and catch up to the cruise ship and embrace twitter as a top tier social media tool?

Thank you for your willingness to help and your grace for the technologically challenged.
