To read and write blogs you simply need a working web browser.
I think you have to give email during registration in the blog sites.
You habe to register with yahoo and create an email account . Then you need to create your webpage at geocities or you can blog at yahoo 360
Once you've created a blog all you need to do is start writing new posts about things you know or care about. Blogging means helping. It's that simple. Think of it like this: When you get a decent email forwarded to you, you delete it, right? What do you do when you get an AWESOME email sent to you? You forward it, right? That's what your blog posts need to be: AWESOME! Help people solve a problem and you will rise to the top in the blog rankings in no time at all!
