Write yer effing blog.
To start blogging one needs only to have a blog. Blog platforms, such as this, Blogger, is a perfectly fine place to have your blog. You go to your google account, or create a google account if you don't have one. Then find Blogger, and follow instructions for starting a blog. Create a new blog. Write up a post. Publish it. Read it on your blog, and decide you want to edit it. Go to back to Blogger, to your own personal workshop for your blog, and make changes. Update. So easy. Ask for help if it is confusing. Should you ever feel like you need to control more aspects of the blog experience, you can always arrange for that later. But if you want to write and share ideas and images, and be able to tell people where they could find your writings and such, blog on a blog platform. Spend your time creating content, rather than managing a web presence.
