I think it is safe to say that if you are being considered for a job - you will be googled. Not everyone is googleable - but a vast majority of us are.

If you google me for example - the first 5 results are:
1. my blog
2. my blog
3. my blog profile
4. My facebook public profile
5. My linkedin profile

The point I am trying to make here is that you should be wary of what information, public information, about you is online. I use the job example, because that has its obvious effects. (However, I guess it could apply if you are interesting in dating someone you met at a bar, a long distance relationship and/or are just simply curious.)

I check my google status often - do you?
