To start a blog you need to know very basics of Internet which you can learn on ‘the online world’ itself. There are many websites which offer you free blog creating services. For example, Google maintains a blog service called Blogger which gives you all the tools to get you started with the blog. However, your blogs then display Google ads. If you do not want such display of ads on your blog you may opt for Wordpress which is one of the most used open source blogging platform.
Irrespective of which website you chose for blogging, you will be only required to fill out a simple form in order to create a blog. However, some websites are more flexible than other. You can look at the comparison of free blogging platforms at http://blog-services-review.toptenreviews.com/ .
Maintaining your blog
Maintaining a blog can at times be a greater challenge than starting a blog. For your blog, you may want to have a good reader base who are interested in your posts and who post comments. For this, it is a good idea to keep posting regularly and interact with other bloggers through comments etc. The idea is to get very active on the Internet and be part of a community of bloggers. Apart from this, you should also frequently check for new comments on your blogs and delete those which may be offending. Blogging softwares equip you with the ability to ban any member from posting comments who you do not like.
