I didn't know about blogging until a friend introduced me to it in 2005. I had my 1st personal website in 2004 and it is where I met a female friend who also has a website where she share photos and other stuff. Later on, she made a blog in Bravejournal.com where she posted her daily mumblings, family photos and digital graphic creations. I was in awe at that time and told her I want to make my own blog and she graciously thought me how. So in 2005, I posted my very first blog entry.
