Today everyone and their mother seems to have a blog. Free blog services like Blogger, WordPress and numerous others, make it easy to start your own blog at zero cost and without any specialized knowledge. Thousands of new blogs are started each day, many in a spur of the moment.
People start blogging for various reasons, which need different approaches. If you start a blog to let your friends and family know what you’re up to, the easiest way is to just sign up for a free blog service and start typing away. Many bloggers, however, want to achieve something specific with their blog. They want to promote their business or product, or, just build up a blog with a big readership, so they can cash in on advertising on their blog.
If you are in it for the cash, welcome to the club! But don’t expect fast and easy money. Building a popular blog with a big reader base takes time and effort. Some people want to make you believe that you can make some quick money with blogs and they will sell you a step by step guide on how to set up multiple blogs, quickly fill them with some content and cash in on advertising clicks. Truth is, the only one making money is the guy selling the book.

I agree, but many people seem to waste time getting things perfect. STOP, just get to it. Use wordpress and you can change everything except the content at a later date.
Also post often to keep traffic up.

Yes, you keep hearing this over and over again: content is king! Creating new content (i.e. posts) should be at the top of your to-do-list.
Also make sure your content is original instead of just copying text from article sites.
Setting up a blog (a.k.a. weblog) is easy and free. It only takes about 10 minutes. Writing your first blog entry may take longer. Making your blog look good by customizing the style sheet could take even longer. All students should have a blog, if only to reflect on what they have learned and to record useful information for future reference.
In addition to having a good blog set up, no one is really addressing the “plug ins” that are vital at creating good blog functionality. I have found plenty of information on how to install a WordPress blog, but very little in regards to the types of plug ins that can be used to create a higher functioning site (i.e. membership sites using wordpress).
Blog are very trendy this days but you are wright is not easy to build very popular blog.
I have about 20 blogs and the important thing I find is to keep up the content. Even if only small some times, definitely regular. once a week or month.
