You should! Try the platform with a small amount of NXT! Some fun things to do are:
- buy some NXT with BTC using the peer-to-peer exchange www.multigateway.com (beta)
- experiment with trading some assets (from within the client itself or using www.secureae.com)
- buy some mp3s from the decentralized marketplace, it's in the client (music from www.sinanboom.com sounds quite good!)

Doing these things gives you an idea of the many possibilities 

And finally, read up on the SuperNET idea if you want http://www.coinssource.com/supernets-coin-offering-raises-over-2000-bitcoins-hours/
