Me neither if I am looking for a job I just usually go to online ads. I just do not care that much for LinkedIn I just do not waste the time on there.
I have a LinkedIn account, but I really do not use it. I have some former Co workers on there, but it really has not benefited me that much and I find it to be kind of a waste of time. I have not found any job leads on there and mostly just read an article when someone posts one.
I don't even have a linked in account. I would however set one up if I were looking into finding new employment. Employers seem to take those pages fairly seriously and use them to recruit new employees. I would definitely suggest anyone looking for a new job to have one and to have all of their latest employment and contact information on there.
I've been tinkering a lot with my LinkedIn profile of late, after a "LinkedIn specialist" said it needed some work on it and wanted to arrange a private review. I haven't taken him up on his offer yet but I'm aware I need to keep it relevant and sharp to serve its purpose. So it's a work in progress.
