I'm reading a blog because I'm interested in the voice a writer has.
If I'm finding that voice boring, I'll stop reading - whether or not AI was used.
The generic AI voice, and by that I mean very little prompting to add any "flavor", is boring.
Of course I've used AI to summarize things and give me information, like when I'm looking for a specific answer.
In the case of blogs though, I'm not always trying to find an "answer", I'm just interested in what you have to say and I'm reading for pleasure.
