to think the strikethrough font is used far too often by some people on Mumsnet?

[bibbitybobbityyhat]

It's beginning to get on my giddy goat.

Doing this is not the same as writing something in brackets

I also see people using it for no discernable reason whatsoever. Someone typing a normal paragraph suddenly starts crossing bits out at random.

It is for using when you say something that you know in your heart of hearts you really shouldn't but you want to say it anyway. Or for comic effect as in "I had half a packet of a couple of biscuits with my cup of tea".

IANBU so don't even talk to me.

Dodo was that a deliberate strikethrough fail? The discarded comment that is struck out must always come before the replacement polite phrase, surely:

'I was waking my son up, he is a right pain in the arse quite hard to wake in the morning'

No it wasn't, strike through before suggest a replacement of real thought:

this is what I really want to say this is the pointer version

Striketrhough after suggests an utterance of annoyance or whispered expletive, a 'I didn't really say that' suggestion, which how I wrote it (calling hypothetical son a pain in the arse)

There's hardly grammatical rules for strikeout is there , no doesn't look like there is, any ideas anyone has about it being used 'wrong' simply means 'not as I think it should be used'.

Pointer = politer

Random auto correct going on there!!

It's a form of punctuation; strikethroughs should be muttered.

And colours are always in CAPITALS.

Colours are in CAPITALS? What does this mean????

Yep.

why hasn't my DS been moved up a book band

I have banded books. I didn't know about capitalising the COLOURS. How many children must have suffered because of my ignorance

There aren't any grammar rules for strike outs as far as I know but grammatically those commas are incorrect.

Capitalising coloura is weird.
Dd doesn't recognise capitals yet.
bolded would work though, for emphasis
