Adding a linkedin url to you CV

Hi,

I have just finished listening to the resume cast and wondered what the community thought about including a url for your public linkedin profile

I can see the following

Pros

If your CV has worked and the recruiter wants to know more, then there is a any easy way to find out more before dedciding to contact you, may be a con

Helps keep to the 1 page guidance and there is still the option for the recruiter to dig deeper

Cons

Need to keep linked in up to date, though this is something we should all do anyway

Any thoughts

Thanks
