We had a post not so long back about the endorsement 'erm feature, and the same concerns were raised there.
The entire concept is based on all users being trusted professionals who wouldn't dream of doing *** for tat (oh come on PC boys, sort yourselves out) endorsements simply to raise their profile.

I was a little dubious about that assumption, when you then back it up with celebrity emails, it's shown to be complete drivel.

Haven't been on it for a while, and I may never go there again. If my inbox starts getting full, I shall simply cancel it. I'm on other sites including this one where the judgement of my peers has far more value than pressing Like on the basis that I'll get liked back. Even the people who don't particularly like me, don't take me for that sort of arse.
