I absolutely agree that our online reputation operates as a de facto CV, and you need to do your best to present yourself in a good light, just as you do on a paper- based CV. Everyone working in the IT, digital, sales and marketing spaces should have an account with LinkedIn, LinkMe, Plaxo and other resume-type social networking sites, as well as tools like Twitter. (The other side of this coin is that if you have a Facebook account, potential employers may be able to find that photo of you tired and emotional at your mate's bucks or hens night - like it or not, you need to be careful about what you publish about yourself online.)

But I have to ask: Does everyone need a blog? With all the opportunities available to publish your credentials and update people about your activities, do you need to share your thoughts on life, the universe and everything through a regular blog, as well?

I'm not knocking blogs (this is, after all, a blog post), but I think that if you don't have a passion for sharing your views on local, global or business affairs, you shouldn't feel obligated to start a blog, in the hope that it might help you get a job.

It's OK to not have an opinion on everything - let your CV speak (online or otherwise) speak for itself.
