We`ve had a lot of discussion here on the forums about how to build a Web site, what problems to avoid, issues of content, and how to be focused. We`ve also had a lot of discussion about having a life plan before building a business plan.
What it comes down to is that although some people like to play around with this expression, "Ready, Fire!, Aim..." it`s a foolish way to go about a career and business intended to last for a number of years. It`s fine for spontaneous ideas, fun, and general adventure, but not long-term business development.
There`s a famous story about a Russian general whose name escapes me. He was always making "to-do" lists, and made one when Russia entered WW II. At the top of the list was the first item: "Win the war."
The key in life is to have an intent, and be deliberate about that intent. It`s to contemplate what it is you`re really trying to create and accomplish, examine where you want to end up (the goal), and then keep an eye on your objective.
If you don`t have an objective, then the first step is to get one. :-) If you want a magazine, then you need to figure out your intended readers, your market, and how you`ll make money. If you want a consulting business, then you`ll need to decide what it is you`re consulting about.
On the other hand, the name of your blog seems to be about reviewing software. Even there, the question is what specific type of software? Yes, you can fill a niche, but always remember that a niche market is one that exists (a need) but that isn`t being served.
With the complexity of the world today, even the smallest niche markets can sometimes do very well. But you have to decide: What`s the niche? Who is it that needs something, who can`t get that something, and that you can help out with specialized knowledge and/or products?
