What do you have to lose by joining in besides the cost of the set? You get to play with Lego again, and you get to flex your creativity by making your own model. You also get to potentially learn lots of new and cool building techniques by seeing what others come up with. There really is no downside to it at all except for you have to spend less than $20 to buy the set.
Join the party!
You've convinced me, now I just need to get a hold of a set.
