I'm a pretty terrible writer. I just spent 3 hours writing and rewriting my first blog post and it still doesn't sound right. I know it's a practice makes perfect kind of thing, but it's still pretty discouraging.
What are some of the blogs that you follow? I'm hoping that I'll be able to pick up one or two techniques from some of the top blogs on HN.
My blog: http://blog.grooovy.me
(if it doesn't load, try again later. Sorry! the DNS was just updated to reflect the new blog URL)
Since then I have written hundreds of articles, a 270 page book and hundreds of thousands of words.
There truly is no substitute for practice, but its the right kind of practice that works.
I would highly recommend reading www.copyblogger.com, which covers all the major tips and techniques around writing online (Make sure to dig deep into the archives).
What you will find is that every few articles you read you will pick up a tip and if you make a concise effort to implement the tip into your next article then it becomes almost second nature and your writing improves immeasurably.
For now make sure your double if not triple checking all your posts looking for ways to make them more readable and fluid and get reading about writing techniques and skills.
