Walkin' On, Walkin' On, Digital Grass...

I'm trying to figure out, just what does it mean to walk on digital turf? I regularly read Angela Thomas' posts on her time on Second Life, and I'd like to know more about youth literacy practices online, particularly those practices that involve a virtual reality, moreover embodied sense of multimodality. So, tonight, I joined both Second Life and Habbo Hotel. On Second Life, I'll be myself. On Habbo I'll be myself, talking with others, etc. but on a site designed for 13-18 year olds. It's been a while since I met the age requirements there.
