Bad. You can't say "I am now going to tell you why......." after you've already stated the reasons. Your introductory should be short and sweet. "I used to like Facebook more, but twitter really grew on me, and i actually prefer it. Here are some reasons why i prefer twitter over facebook."

That's good for an introductory, or you could also say this at the end of the above paragraph.... "the reasons i prefer twitter and facebook are (point 1) (point 2) (point 3)" and then go in detail about each point.
