I haven’t done a real study of this, but I watch as some networking sites in my demographic become more and more popular and others decline.

Firstly, there are those people who have jobs and are not that interested in making money from the internet. More and more of them appear to be joining Facebook. My age group isn’t going for Myspace. My friends are using it for advertising social events and it seems to work quite well. Then again there are still those real life friends of mine who would never join Facebook because they don’t want their information anywhere on the net. A natural fear, but one which doesn’t have to be frightening if one is very clear about what one writes down and shares in terms of their lives.

These sort of people would probably use Skype as well. Skype has improved a lot with video and webcams so that you can see your companion. Skype too is used by people who do actually find people in the world who they would like to become more familiar with in real life. There are at least two people I know who have created romances using this form of communication.

Blogging is really for those who hope to make money from the internet. Well, I don’t know about you, but my Google cheques are really drying up and I’ve heard the same is so for other bloggers and web site owners.

Twitter is really taking off and there are so many applications for Twitter. It combines well with Facebook.

There’s been at least one traffic generator I know of which has closed down – BlogRush. So there must be more.
