all the choices you suggested are possibilities, but also I give you one more posibility:
No Comment on my blog can mean that I have a lot to say about a specific matter, maybe a book to say, or maybe a vague delima is in my mind. I maybe want to share a vague feeling, without disclosing the details. I can email you a vague yet a more specific detail in an email if you were interested ;-)
btw my favorite one is 'he wants ice cream' :-) I do, how did you know? ;-)
