When I was looking for someone to comment on their blog I looked at their two hobbies. I searched for one of their hobbies to be something we have in common, and the other hobby to be something I know nothing about but want to learn more because it seems interesting. I also looked for what country they lived in. I wanted them to live in a different country than me. I choose someone that was one year older than me on purpose too.
Once I found the person I wanted to comment on, I read all of their posts. I then picked the post of theirs that I wanted to comment on. When commenting I was sure to first, complement their post and describe what I liked about it. Then, I told them about how I could relate to them. Next, I asked them more about themselves. Lastly, I gave them my blog information and nicely ended my comment.
