Well, I'm in my 20s, and I wish I had some really good advice for you. I guess my generation pretty much uses the internet for everything, whether it's on a computer or a Smartphone.
But we're a varied group of people just like any other. For instance, I make my own soap, I'm obsessed with real and whole foods, and couldn't care less about fashion- I have girlfriends who have office jobs, eat Lean Cuisine and list "shopping" as one of their hobbies - I have male friends who are artists and musicians and gym-goers and all other sorts- I know a lot of people my age who are college graduates that are seriously under-employed, and even more people who are back in school because of the crummy job market. I know a girl with a Master's degree in Biology who works at Dominoe's Pizza.
We're a pretty lost generation ;). Most of us are already in debt up to our eyeballs. It's hard to imagine that we're the next "reigning populace" - I think that's going to be a sad thing!
