It doesn't matter if you are in business or not. Every business needs to have a website in this day and age.
If you want to reach critical mass, or even just any mass, you need a place to send people to.
You may not be in business, but you too need a website. That job you just applied for is hanging in limbo right now. Will your prospective employer 'google' you? Will they find your MySpace page or those pictures from Spring Break 6 years ago?
Or will they not find any information on you, or worse yet, information on another Brian Smith?
The easiest way to take control of the situation (and often free) is to start a blog. www.blogger.com is a great place to start and is a free blog platform. Mention your name a few times (or give your blog your name) and your chances of coming up towards the top of any listing have increased tremendously.
Take control of the situation by creating a website or free blog today.
