Super Injunctions

I see that thanks to twitter we can now "find out" who has obtained super injunctions and what they are for. Question is - so what? Does it really matter if we know/don't know who has been having affairs? I can understand the public interest if it is someone who takes a high moral stance; members of the clergy (any faith/creed); politicians - if they cheat on the ones they profess to love what do they do to their constituents? But footballerss, showbiz types etc - whoever thought they were paragons of moral virtue in the first place.
