Facebook and MySpace--Sticky?

Having had a Facebook account for some time now, I never really thought of it as being sticky. While there are a few gadgets on Facebook such as "pokes" and words automatically linking to other Facebook pages (example, names, titles, fan clubs), most if not all were internal Facebook links. Facebook's emphasis is definately more on communication, friends and sharing than MySpace. After setting up my account in MySpace, I was "stuck" ! Not only did I spend too much time figuring out my profile page and the like, there are more options to play with. (examples: music, videos, applications, my blogs, etc.) I could easily get lost in another world of videos or music by simply clicking the music or video tabs. The advertising on MySpace is more blatant, and once again I could get lost in a game or featured application by simply clicking any of the flashing ads on the right. I could also spend time setting up My Music and My Video on my profile page and change it whenever. While I find myself connecting to Facebook to visit my friends and communicate, as well as to have some fun, I'm not sure I need all of the "stickyness" of MySpace to do that. Perhaps younger users would welcome the distractions.
