I hang outside in my back yard every couple weeks, just to test things out and make sure I'm not losing my touch setting it up quickly. There's a small, but nice wooded area in my yard where I can hide from the neighbors and most of them have fences anyway so it's nice and private.
I'll admit, I set up my MSR Hubba just the other day since I'm bored and just messing around with gear, itching to get back outside! Hammocking is WAY better, but I'll probably still use it now and then. After all my hammock trips, it did feel nice to sit up inside the tent on a solid surface and spread out on the mat.
