[M]ost bloggers start a blog because they want people to come to their site, subscribe to their email newsletter, and eventually buy their products. …
The content soon reflects these motives and the blog is dull, boring, and uninspired.
… [I]n the end, the blog shrivels up and dies.
Blogging for profit is doing things the wrong way around.
The purpose driven blogger asks “Why would someone read my blog and give me their email address?”
The difference is as subtle as it is profound.
If you have a blog, make it a site you would actually want to visit and read yourself. If you do this successfully, you can absolutely expect to profit from your blog (in the form of clients, obviously, when it comes to law blogs). But if your purpose is profit, you probably won’t.
