Tens of millions of people around the world have started weblogs, or blogs, in the last few years.

Some are good, some are bad and some are so embarrassing you wonder how the writers can go out in public.

One of the reasons blogging has become so popular is because they are very easy to set up.

You can go to one of the blogging sites, register, choose a name and a design for your own blog and be off in minutes.

People have lots of different reasons for blogging. You might want to share information about your hobby, or comment on events around the world.

Or you might just like having an online diary.

Blogging started as a way for people to reach others online, and it's still largely a screen-based occupation.

But some people are taking the blogs off the internet and into print.

Blogs that have been turned into books include Russell Davies's, whose blog about great British cafes became the book 'Egg Bacon Chips and Beans'.

And now there's even a prize for the best blogger turned bookwriter. It's called the 'Blooker' prize, a joke on the name of the Booker Prize for novels.

The prize is sponsored by Lulu, a US-based website that lets anyone who has written a book get it published.

Instead of having to pay out for typesetting and printing, then finding yourself with five hundred copies of a book that nobody wants to buy, Lulu makes it a lot simpler.

You put your work on their website and anyone who likes it can buy a copy – as a real book, not just as a digital file.

The book is printed on a high-speed printer, bound, and posted to them. And the author and the site share the money.

It may not challenge Waterstone's yet, but the idea of printing books when someone wants to buy them instead of keeping them on the shelves or in a warehouse may well take off.

Big publishers like Cambridge University Press already do it for some of their books, and others are likely to follow.

And it means that regular bloggers who reckon that their words would look even better in print than they do on screen have an easy way to make it happen.

Sometimes you look at a new gadget and realise that your life won't be complete until you have one.

There had been portable music players around for years, but they were definitely only for technology freaks until Apple launched the iPod and made them cool.

When mobile phones turned from bricks into sleek toys that slipped from pocket to hand, we all went out to buy one.

And once the designers got to work on digital cameras and realised that they didn't have to look like old-fashioned cameras, the market really took off.

Now Microsoft and Samsung hope they can do the same for the computers we carry around with us.

At the moment there are laptops, usually with keyboards and reasonably sized screens, and there are handhelds, which fit into a pocket and aren't nearly as powerful.

Microsoft reckon there's a gap in the middle, for a computer that's a bit bigger than a paperback book.

It could be used to write on or to surf the world wide web.

But it would also do for listening to music, watching our favourite movies and tv shows and even reading electronic books.

It's an exciting plan, and there was a lot of eager anticipation before it was revealed to the public earlier this month.

But what they've come up with doesn't seem to fit the bill. Yes, it has a good size screen and you can use it for lots of different activities. But it's heavy, expensive and the batteries only last three hours.

And it goes by the really exciting name of the 'Samsung Q1'. Some people don't see the point anyway, as they reckon our phones will soon do everything for us.

But it's surprising how quickly we can learn to love new technologies, if they look good and make our lives better.

I can see why Microsoft are interested in selling us smaller computers. It just might take a while until someone gets it right and we all want one.
