A blog (short for “web log”) is an online journal made up of words, photos, videos and music. It’s usually written with the latest entry at the top and can either be private (ie only people you choose to invite can read it) or public (ie anyone online can see it). There are millions of blogs on the Web.
Blogger.com describes blogs as “…a personal diary. A daily pulpit. A collaborative space. A political soapbox. A breaking-news outlet. A collection of links. Your own private thoughts. Memos to the world.”
Micro-blogging – where you publish brief status updates online – has become very popular. One of the best-known micro-blogging sites, Twitter, asks one question “What are you doing?” and answers must be fewer than 140 characters in length.
You can choose who sees these status updates, which are known as “tweets”, and decide whose tweets you’d like to follow. If you choose to follow someone on Twitter, you’ll get their updates on your Twitter homepage when you log on.
As of September 2010, Twitter had 175 million registered users and around 95 million tweets were being posted each day.
As internet access is now available on many mobiles and other portable devices, it has become even easier to blog or tweet while you’re on the move.

Your son or daughter might enjoy talking about stuff that interests them, expressing their opinions and staying in touch with friends on their own blog or Twitter page or they might take part in a blog or Twitter page run by their school or another organisation. They might also read other people’s blogs or Twitter updates (written by their favourite author or band, for example) as a way of keeping up-to-date.
As well as blogging websites like Xanga and LiveJournal, social networking providers like Bebo and MySpace offer blogging tools.
Whilst part of the fun of blogs is that you become a “published” writer, the fact that other people can read about your life could present some risks. Younger bloggers and Twitter fans need to understand the potential threats to their online safety and privacy, such as:
What you need to know to get started
Technology is part of your child's life before they start primary school. They're probably using the computer, the internet and interactive TV for fun - watching programmes on the CBeebies channel and website or taking part in the Club Penguin chat rooms...but they still need adult guidance and supervision.
If you have 8-11 year old children, your house is probably full of technology - PlayStation, Nintendo, iPod...the list goes on. In fact, research shows that 8-11 year olds in the UK have an average of four media devices in their bedroom.
This is a crucial age for young people to embrace new technologies and develop their ICT skills both at home and at school...and it's a crucial time for you to take control when they start exploring the digital world as well as the real world.
They're at secondary school and growing up fast. It's a time of change and their digital world might seem as important as the real world to them. They might spend their evenings on Bebo, Facebook or MySpace ; watching videos on YouTube and uploading their own for others to watch; or doing research for their homework.
You want to encourage their technology and social skills, of course, so it's useful to understand what they're doing with technology and to get involved with it.
Once your children are teenagers, it might be tempting to think that they're tech-savvy and dealing with everything the virtual world can throw at them. You probably watch in awe as they switch from chatting with friends on Facebook to updating their Twitter profile; playing against someone on the other side of the world on their games console to downloading music on their mobile.
It's all great fun but, as they get older, the things you need to help them to cope with in their digital world are ever more challenging. Far from leaving them to it, you really need to keep communicating with them.
The average Facebook user has 130 friends on their profile
