Wordpress?

Does anyone here have a wordpress account?  I was talking to my cousin, Lerma about other places on the net that I could blog on and she mentioned this site.  So I decided to create an account, but for some reason it seems very confusing to me.  (Am I just slow?!  Lol)  But I'm just wondering if any of you gave wordpress a try?  How do you like it?  I wanted to use it to make another (or my main beauty blog instead of my D.G.S.Beauty blog).  The only thing that really intrigued me is being able to create my own domain and choosing between .com, .net. or .org.  It's $17 a year ($7 more than blogger).  I do love blogger though.  I can't decide...
