Although most people feel that generating ideas to finished articles is the most daunting task associated with blogging, it's the technology curve that is the real challenge, there are many strategies that will help you overcome this task.
Mining Your Email
One of the easiest ideas to generate content is mining your own email. Your goal is to find situations or stories where people can learn from your actions, benefit from advice you provided, or become aware of something of value.
Example: If you helped a first time home buyer find a great tool (mortgage calculator, school, referral) that made a difference in their experience. You could provide the valuable information and the positive results.
WARNING: Tone is Everything in the Blogosphere
The biggest, most difficult mistake to eradicated when learning to blog is the tone of your articles. The blogosphere is a place where valuable information is provided continously without strings attached. Do NOT make your blog posts advertisements or sales pitches about your listings, your services, or your business. Provide valuable information and watch what happens as your traffic will grow.
Realtors that write posts about their listings, their services, and the things that make them the best will never garner readership; this violates the most basis blogosphere rule--NO sales pitches allowed.
Good idea about mining the emails for articles. I will do that more often. I have gotten a few off of emails.
