Even though blogging is so annoying and I'd much rather be doing something more enjoyable like eating, it can sometimes be a good thing. When writing a blog you can literally take it anywhere you like. It can be made super personal to the writer or it doesn't have to be in the slightest bit serious. If you feel strongly about something it's a great way to get your point across, people may dissagree but it really doesn't be matter because it's only your opinion.
