What about just starting a free blog on wordpress.com or similar?
My old blog was on wordpress.com and it's a really good platform, easy to use and people can subscribe so that they are notified when you post something new.
Plus you can choose themes so your blog can look the way you want, you get statistics so you know how many people are reading it. And you won't be limited by the 200Kb file size limit like on this forum.
And did I mention it's free, with no ads
