These are general journalism questions, but I hope you will answer them please.
Why do articles about women always mention their age?
Absolutely no good reason. Any more than there's any good reason to mention the value of someone's house. I think it's in fact yet another example of everyday sexism.
Why do sports sections feature so few articles about women's sport?
No idea, I'm afraid. I have never written a single word about sport (women's or men's) and have never participated in or watched sport of any description, so I'm probably the wrong person to ask! That said, I think it is probably because there is, for whatever reason, less interest in women's sport.
Why do journalists pad out their articles in an annoying way? (example is something like "It's a truth universally acknowledged that Actor Bloke is a sex god..." when it is boring and obvious that it is padding, and I don't particularly agree with it?
An interesting question for many reasons. I'll use your example, but it could apply to anything, really.
Let's say Actor Bloke is generally regarded as a sex god. I personally find him desperately unattractive. Yet there's a weird way in which things are repeated so often that they almost become true. And then they are repeated all the more, and become (apparently) even more true.
For some reason, popular culture seems to dictate that certain people/organisations/whatever are deified, while others are demonised. It's a very strange process, and is largely incomprehensible. In a similar vein, why did the colour grey suddenly become ubiquitous? Who dictated that grey was the only neutral that anyone would want to use?
Why do people write about themselves and their children in the lazy section? Are their children going to be pleased about the 'oversharing'?
Another very good question. People write about themselves and their children because those features command good fees and a lot of online comments. I think there comes a point where you can't use your children, however tempting the fee. But each to their own.
