I used to use blog several years ago when I was still in China. At that time, there was no Microblog like twitter, Wechet, etc. I usually wrote my stories and emotions every day during that period. My close friends can know what I was doing and how I felt that day. Besides, I would also post some beautiful music and my travel diary with video and pictures. They coud comment on my blog frequently.
I do believe this is a good way to share interest and stories with good friends.
Nowadays, we generally use microblog to communicate with my friends here in Canada and in China. Social media has connected the people all around the word, which seems we are living in the same time zone and an no barrier at all.
