Who has a Blog? Just about everyone. Why, because Blogging opens your World to a larger number of viewers and allows You to express your opinions, hobbie's, and views on any Topic you desire, You are the Author, controlling the Content and Design of your very on Page on the Net.
Who Blogs?
Bloggers range from people expressing their feelings on a number of Topics, rangeing from cooking to space travel, and everything in between. Marketers with Websites that sell a product will use Blogs to drive customers to their Primary Site.
How?
Once you have determined what you want to blog about, you join a Site that gives you a Free Blog, with Templates and Tools needed to create. Several Sites exist that offer an easy program that will have you up and running in minutes. One very good one that I use is Blogger, another is Wordpress.
Once you have created your Blog--with all the Bells and Whistle's, you need to get your Blog "out there"--to be noticed--Blog Directories. You join, submit your Blog, and you have a community of Bloggers checking out your Blog. You also can view their's--this gives you a good look at how the experienced Bloggers design and Promote their Blogs. There are MANY directories to join--a starting point would be http://technorati.com.
Another source that is useful and Fun is http://entrecard.com, here you will create your calling card, visit other Blogs, drop your card in their Inbox, they in turn visit your Blog, this will increase the Traffic to your Blog. Another Site using the same principle is http://spott.com.
The sites I recommended are Free, and there are many others, join as many as you like. Keep your content up to Date and your viewers will increase.
So, jump in, start your blog and Enjoy.
Perhaps a bit more in depth would be beneficial to everyone.
