Submit blog, a new world
On the part of the blogger, it is important to bear in mind that you are essentially writing for a global audience. Although you may still adopt a personal tone if you wish, remember that other people who may not readily understand your tone or your delivery may read your blog. Blogging was originally used as a way for people to get their thoughts out on the Internet regardless of how trivial or insignificant they may seem to be. There is certainly nothing stopping you from doing the same today if you wish, although you can hardly expect everyone who comes across your blog to be interested in the minutiae of your day to day life. Instead of merely posting about your day to day activities, it may better serve your blog to write on a certain theme or subject.
