This question reminds me of the time I was first online, circa form 3 (2007). I decided to investigate when I was first online, and first blogging. To determine when I was first in contact with internet, I traced my hotmail account to its earliest mail. It was 17/February/2007. I still remember I created this hotmail account in a cybercafe as I do not have a computer yet. Immediately after my first email, I created my Asiasoft account, to play an online game called Maplestory.
My first blog post can be traced to August/2008, a year after I got on to the internet.
My first activity on Facebook is on 14/October/2008.
