A generation behind - what can I do to catch up?

[Hammurabi]

Essentially, I was born to "baby boomers" late. I am supposedly from "Generation Y - the Internet Generation" but I was brought up on little internet/technology. After Palm Pilots - a predecessor to smart phones, technology savvy...died in my family - the majority of the social network was cut off to me from 2004 to 2012. So, I've spent 8 years out of the loop, missed many (what I consider) awesome things, and lack the skills to navigate the internet and utilize internet apps (artistic, ma thematic, and writing ones in particular) at the speed of my peers. It is like I am between the X and Y generation.
A) Besides a plethora of games, virtual pets, and forums, what did I miss?
B) What is/are Generation Z (today's kids and preteens) working on/looking into?
C) What can I do to catch up to my peers at a reasonable pace?

I would ask for understanding and help in this.
