You you're a MCSM fangirl/fanboy when you tried to build one or more of the following:

•The Witherstorm
•The orders fortress/towns
•The Amulet
•Endercon
•The chicken booth
•Ellegaard's Redstone Stuff
•Soren's Loot Room w/ minecrafts :)
•The Railsystem in the Nether

I'm probably missing a bunch, but you get it... I hope.
