and how do you stop your competitors using the information against you
the more information you put on social media, the more leaks out for your competitors to use against you
unless you have closed groups with everything locked down you provide head hunters, competitors and every man and his dog access to your skill base and internal information
putting anything other than marketing information of social media is commercial suicide
imagine if you had uploaded a number of PR photos onto something like instagram, you then find out they have sold your images to a competitor because they changed the T'c and C's
the company i work for tried something similar with a closed system which was outsourced so the management could trawl it for skills etc, when asked if we had to put all details in we were told it was not compulsory so 90+% put just the minimum name and address in
the data was offshore with no safeharbour agreement and outside EU DPA area, sorry not going there and HR could not answer questions on data security, at which point BIG fail
the only people interested in these sort of things are those with a vested interest in getting their hands on your personal data
