I have just discovered a new element of the Google range and that is the public Google profile - here is mine: http://www.google.com/profiles/sarahstewart07
Having a public Google Profile will increase your presence on the Internet which is particularly important if you want to promote yourself online for whatever reason. The instructions on how to do it can be found here.
What I like about it is that it very easily hooks in your other online channels like YouTube, Slideshare and blog accounts. Let me know how to find your profile - I'd love to have a look to see how you use it.
