Long before these silly sites, I was examining the progress of a project that was running behind schedule (by 18 months). They were only putting TAG spreadsheet data into a database for maintenance scheduling. I and two other people scrapped what had been done and started from scratch. In six weeks the maintenance program was on board the Oil Rig and being used by the engineers. What has this to do with social networking? Well when the computers they were using were examined they had over 10,000 number plates entries and were doing a bit of business on the side. None of those caught out raised one objection by quietly slithered away hoping their reputation would not follow them. Your item 10; I do not agree with an employee should not be giving any company information to employees of other companies. (You want your employees to know what other companies are doing and to be in touch with the heartbeat of your market. What better way to accomplish this than with social networking? Yes, they can network with email, but not on as grand a scale). I think it is obvious you have not been in any business that holds trade secrets that have been developed in-house, otherwise you would been singing from another songsheet. I don't often find myself hostile to most of what you write, but in this instance I would stay "stick to what you know." Don't change your day job!
