Facebook is an incredibly popular piece of social networking software, which is used all over the world. However, it has come under criticism for many controversial aspects of its layout and usage. For example, extracting your profile from the social network is something which is actually surprisingly difficult; this is because when you choose to delete your account, the default option is to actually "deactivate" it; if you don't untick this box, then your profile is not completely taken offline and deleted, but it is only your public profile taken down; this is supposed to make it easy for you to return, as you don't have to put up your information all over again. Also, the relative openness of Facebook means that employers can trawl for "digital dirt" on sites such as Facebook.

The web is an incredibly powerful and versatile tool; however, it is also extremely open. This is, however, something that people often forget - that whatever you publish on the internet, be that blogs, or anything, has an invisible audience: one which you do not, and cannot know about. But as people often forget about his, and publish aspects of their lives which they might not want potentially anyone to read. This makes the web something which can also be relatively dangerous; chatrooms, for example, can be accessed by anyone, and was how many paedophiles groomed their victims. Although this is a very extreme and rare case, there are other more common examples of the lack of web privacy; on Facebook, for example, if you are part of the London network, your profile can be viewed by anyone on that network, which currently has over 5 MILLION profiles.

Standard blogging is extremely popular, and is growing at an incredible rate. However, microblogging is a form of blogging which is becoming increasingly popular across the world. The concept of microblogging is that where you write short sentences which describe what you are doing at any given point in time. The problem with "proper" blogging sites such as blogger is that they are designed to hold longer posts (such as what I am writing now), which is inconvenient if you want to write something short and snappy. Probably the most used microblogging site is Twitter, although Facebook and other similar applications have microblogging elements in them. Microblogs can be easily updated, and now sites like Twitter are available on your phone, they can be looked at and updated almost anywhere in the world. Celebrities like Stephen Fry are increasingly using Twitter, as it is an extremely convenient form of blogging.
