Blog about Twitter

In blackboard's discussion board, each of us will have our own thread. We need to click thread according to the title to see the specific explanation of our classmates. In blackboard, we just select one or two classmates' threads to open and reply. Moreover, in the discussion board, we have specific topics to discuss, all posts are about specific topics. All topics is listing on the board. On Twitter, however, everyone's posts appear on the home page, and we don't have to click on any topic to see everyone's posts. If we need to add a specific topic to the post we just need to tag it. After adding the tag, we can see all the posts on this topic in the tag. I think twitter is more interesting and convenient. I just need to scroll down the home page to see what all the classmates have to say. Also, it is to reply to my classmates' tweets.
