What means “blog”?. A blog is nothing else but an online notepad where you can easily add notes: texts, images, sounds or videos. What blogs have changed is the way a website can be updated. With blogging software you don’t need to open the whole file of your website and deal with it on your web editor to add a short note, now you can just upload the new portion and it gets automatically aggregated to the whole site in reverse chronological order (present to past). The blogging phenomena is all about a technical alternative to editing websites, nothing to do with website content. Blogging is trendy and cool, but only if you have interesting things to say and to show to the world.
