Twitter and Blogging

I am an expert to Facebook.  I have been for about 5 years.  I love it!! It is so easy for me to work, i know where everything is and what everything means.  WHAT IS WITH TWITTER?  I am completely clueless on how to work Twitter...and completely clueless as to what the point of it is.  I feel like Twitter is almost stalker-ish.  You "Follow" someone? That just sounds a little creepy to me! I noticed people started hash-tagging on Facebook.  Whoa whoa whoa now, lets just keep this to twitter.  I'm already overwhelmed just looking at twitter.  I do not need Facebook and Twitter to start blending together now!! Until next week... Off i go to try and master Twitter.
