A blog is like a news paper or magazine but the difference is that here you don't need to bear all the expenses as it is on internet and free and paid both.
A blog is like a website where you can share any news,ideas, photos, videos, audios, etc that too free of cost.And any body can see your blog from any part of the world and you only can edit your blog.It means you can communicate to the masses all over the world without any problem.
I also have a blog where i write something whenever I get some time.If you are willing to write a blog then first choose a good name and setup a blog on the www.wordpress.com/ or www.blogspot.com/ as these are the best as I think.
Then design your blog accordingly choosing the right template and then think about the topic what you want you write about.Or what subject you are expert in so that your information can be useful to the readers who read your blogs regularly then only he will come to read your blog regularly after a particular period.Better to write at least one article in one week regularly.
By blogging you can spread your information your knowledge or message to the world without any cost so it is also becoming a good mode of communication.
You can also earn from your blog.If at some time thousands of people are reading your blog each week or month then you can display advertisements on your blog either these advertisements can be placed by google adsense or amazon.com or ebay.com or any local businesses.
But for that you need to know how to get lots of visitors to your blog, then only you will be able to get income from your blog, it is not easy task you will have to dedicate yourself to promote your blog, for that you will also have to give some useful information to the visitors so that they come again in future to see your blog.
