From my head on blog blogging
It is most common type of blog and it is more traditional. Interestingly, some personal blogs are never read by any person but individuals generally maintain these blogs for their own satisfaction. One example of a personal blog is 'microblogging' which is getting very popular. Twitter is a kind of microblogging where you can submit blogs and interact with your friends. Another famous types of blogs are corporate blogs which can be private or professional and usually people cannot submit blogs on these blog websites.
