LinkedIn generally
Toni - I agree with your comments completely. Well done! The number of outstanding invitations I have where people claim to be friends or have worked with me when I do not have a clue as to who they are is astonishing. Needless to say they are residing in my filing tray. The original idea of a business platform was good (and still can be) and some old fashioned people like myself still want that so, those responsible for the site, please do not treat us like giddy schoolchildren in the playground competing for the largest group of friends and stick with the important relevant reasons for starting it in the first place.
