Personally I like www.linkedin.com I do not use it for recruitment presently, but a few friends have found me via it and some clients have Linkedin, so I can see the value when I need to recruit next. What did catch my eye as I was adding another client, was the “ask a question function” and thought I would take a look, one that caught my interest was titled “Has anyone generated revenues through networking on Linkedin” You may like to read a few of the success stories.
The chap that posted the question was Neil Gibbons who is researching network sites for a business TV series show, it will be interesting to see how he does.
What I did try the other day was to see if there where any food buyers in the UK, as a relative of mine in Spain is looking to sell their Olive oil to the UK market. I just couldn’t believe how many where registered, I still need to follow up but it certainly proves it is a resource that should be used and my bet it is it is not used to its full potential in the UK.
