What's the point of blogs?

Weblogs help everyday people, from all over the world, transfer news to the rest of the world.
All types of people keep blogs; politicians, celebrities, sports personalities and many more.
A web blog is no different to any other web sites except that they are usually writen about something specific.
It is hard to distinguish and differentiate between a blog and a normal website. There is no exact cut-off for what a blog is.
You can use blogs for posting news about yourself.
For example, people will write about a trip they're going on and tell their readers of all the exciting things that had happened and keep them up to date with what they're doing.
Weblogs first came into existence just over 11 years ago when John Barger started to write daily posts and put links up of things that he thought were interesting (things like politics, books, culture, etc.). People started to catch onto this idea and started creating their own blogs about themselves and the things they liked.
Some people use blogs as online diarys and put a lot of personal information online for everyone to view. People do this on social networking sites aswell, sometimes by accident, and that is why you should always check your privacy settings regularly setting them to your level of comfort.
It's important you do this and that you are aware of the dangers of sharing personal information to anyone that you dont know.You should be aware of this, but also accept the internet as being a tool to share things and be accepting of it.
Another main feature of blogs was the creation of RSS (Really Simple Syndication).
This allowed people to customize their blogs and show what they were interested in and share it with constant feeds from their favourite websites.
