Dear Vicki: As a jobseeker, should I rely on LinkedIn, or is it still all about who you know in Ireland?

Q: I recently took a redundancy package, and I am now job hunting. I’ve been told that ­LinkedIn is the place where I am most likely to find prospective employers, and have dutifully changed my avatar to “open for work”. However, I have a feeling that Ireland is still all about “who you know”, and I may do better by working my network of contacts. Is it worth paying for a full LinkedIn subscription, or what is your experience of modern job hunting?
