I'll give you Reddit and (most of) SOPA. But Google and Wikipedia are definitely GenX products; we'll split the difference on Obama, and the wars ;-)
I looked up the technical definitions of Baby Boomer, GenX, and Millennials. Baby Boomers end at 1964. GenX ends in 1984. Millennials (GenY) end 2004. The current generation is Generation Net (GenZ), and will end 2024.
So I guess we Millenials haven't really done much yet... but GenX (Today, ages 28 to 48) are just getting into political leadership. Obama is still a Boomer, but GenX candidates will certainly be up for election this decade. A GenX President is unlikely for another decade or so... but surely House / Senate members are beginning to be filled with GenX. So I guess you guys have first dibs on fixing all of these issues, eh?
Don't mess things up too much before we Millennials get there!
Governments change, be it to external factors (9/11 -> passage of Patriot Act -> PRISM), or internal factors (Erm... the Civil Rights Movement)
We, the Millennials, have a good shot at becoming the next greatest generation. We grew up during the rise of the internet. We witnessed 9/11. We fought in two oversea wars, we've returned to the greatest economic recession since the great depression. We've elected the first African American President. We've defeated SOPA. We've created Reddit. We've created Google. We've created Wikipedia.
The air of political change is growing... not shrinking. Don't you see? Millenials are beginning to take over the country. Its our time to shine!
