I agree with you very much
@alwaysgreen, many likes are certainly a like due to an interest in the company, of whatever kind. However, you have to link yourself to employees, so make them a contact request or follow them, like I do. Then you will also get the latest posts or activities of these people or companies.
For example, if Rob Telson or Anil Mankar likes it, it does mean something, because they certainly don't have the time to spend hours looking up which employee from whatever company posted whatever news. They don't have time for that. I have that time, but you read quite a lot during the day ;-)
