There are plenty of reasons why you should have a blog. Potential clients may find you through your blog. Other attorneys might find you. You can develop good content that makes your blog a useful resource for potential clients.
Another good reason is that it can help your writing skills and help showcase your personality online.
Practice makes perfect
Writing blog posts is completely different from legal writing. Riding a bicycle is different from playing volleyball. At the same time, both activities are workouts and can keep your body in shape.
Think of blogging the same way. Writing everyday, or even once or twice a week, will help you maintain and hopefully enhance your writing skills. You will notice your grammar gets betters. You will notice more tyypos. Most importantly, blogging should help you organizing what you write.
The more you write, the more you will improve your writing skills. Although, I should note that I still get plenty of comments on my terrible grammar skills.
Develop your voice
When people first start blogging, they tend to either create a new persona or simply remove any signs of their personality. The more that you write, the more comfortable you become with letting your real personality come across in your posts.
If you do not believe me, take a look at some of my posts from a year ago. In terms of content, they are fine. In terms of any showing my personality, they suck. For the most part, showing your personality is a good thing.
