Almost everyone I know has set up his or her own blog. It may be of any topic under the sun. Family blogs, food blogs, cooking blogs, fashion, personal, wedding, etc. To my surprise, these blogs are updated almost everyday - complete with pictures! I own one - http://www.thewifeydiaries.blogspot.com. It is a personal blog wherein I share almost but not everthing from getting engaged, to tying the know, and being a housewife in themeantime.
As I have learned, the term blog is derived from the words web log. Logging in rants, raves, reviews on the web. Some say that it's like exposing your whole life to everyone around the world. I think the other way around. A responsible blogger, I think, would know the limitations on what to include in every post he or she makes. Would you post something online about your deepest, darkest secret? I guess not. Well, I believe others do. I just haven't found the links to them. Haha! Other people blog to simply exchange point-of-view on one topic.
Blog hosting sites can be found instantly in one click of a search button. Most of them are free, others charge if you want your blog site upgraded. http://www.blogger.com for instance is a blog site which is very easy to use. No need to master programming or html. All you need is to sign up, create a unique blog title, choose a template, and voila, you're done! You are now ready to enter your very first blog post.
