I wonder what Lionel's opinion is on that?
Oh! You remember me!

Lionel's opinion is that if you can't remember simple grammatical rules, then you should take extra care when committing opinion to paper, or, in our case, submitting opinion to public scrutiny.
In this instance, you have forgotten a Golden Rule:
* never end a sentence with a preposition
And 'is', as the third person singular present of 'be' - is, as such, a preposition.
I also vaguely recall something about people in glass houses.
You now have my opinion.
Sorry to butt in, but the word "is" is a verb and not a preposition. A preposition denotes something spatial, such as during, below, beneath, before, on, in etc.
Nevertheless, Brian Ross' sentence was grammatically awkward.
