"We, Party Maniax, are a young and dynamic party promoter."
The above sentence sounds awkward to me, but I'm not entirely convinced it's wrong. If the author is talking about "we" as a whole, it may be correct to write "a party promoter" instead of "party promoters." Is it?
What about these?
We, General Motors, are an old and enormous car company.
We, Farm Fresh Market, are a trusted and reliable vegetable seller.
What's the difference between my sentences and yours? I agree that they all sound a little awkward, and I would never have expressed myself that way; however, I can't find anything wrong with them.
