Social network and Web2 apps

Popular social networks and Web2 applications:
Twitter - Flavour of the month.
Best for keeping up-to-date your idols, a particular topic (eg. #surfing) and/or members of your team.

Linkedin - How timely.
If you think that there is a chance that you might be unemployed soon; hop on this network (don't look too desperate). Then if the crunch comes you might be able to use your presence here to get a job or at least to use it as a reference.

Blogger / MySpace / Multiply - DIY websites or a scrapbook.
All those people you call friends are by definition interested in what you do. Put a collection of your stuff somewhere where they can see it. I prefer Multiply for this purpose.

Facebook - "Friend collecting"
As an older person I use it to keep tabs (in a nice way) on my relatives in that Facebook age group. It helps that I am not the slightest bit judgemental.

It is by playing with tools that you learn how to use them.

Before you forward

Have you ever felt tempted to forward an email to everyone in your contact list?
OR to just your best 20 or so friends?

Before you mass-forward email consider this:
They might each be suitably impressed and forward that email to their hundreds of friends.

Remember the game where you placed a grain of sand on the first square of a chess board and doubled the number in each square after that?
If you don't then try it and see what happens.

With that email is not just a case of doubling, it may be multiplied by 20 or a hundred at each step.

That email you are about to forward has as its main purpose getting you to forward it!

I expect that there are systemic ways that it can be prevented from bringing the internet to a halt. But the main way that you can contribute is to not forward it.

You may know employees that have a little more time on their hands at the moment, so this may happen more often than when they were busy.

To immunise yourself against the temptation to mass-forward email visit:
