For or against Blog?

As Jérémy, Klara and Caroline said, I think that posting in a blog has some advantages and disadvantages.

I think that the positive items of the blog are: we can change the date, it's easier to correct grammatical mistakes, we can put some illustrations and we can comment on the posts of our friends.

Now the negative items: I prefer to write in a copybook as although I haven't got the problem of Internet connection, I haven't got the time to write everyday in the blog. .

Although the are more argument for, I am not very fond of blogs...
