Graduated high school in 2007 in Slovenia. Saw the heyday of public IRC chatrooms (city based), tail end of MySpace, heyday of personal blogs, the beginnings of Facebook, but Twitter took off like wildfire in our corner of the world.
Everyone was on twitter, especially tech enthusiasts. My Twitter account dates to July 2008.
My Instagram user ID is sub 1,000,000 :)
The really cool kids in college had hacked iPhones from Italy and USA. I think iPhone 5 was the first officially available for us ... I managed to import an iPhone 4 but missed the jailbreak by 3 days and couldn't use cellular on my phone for years. It was basically an expensive iPod touch. Good times.
