The HNQ feed (a RSS feed for 30 of the HNQs) has questions from meta.stackexchange.com, a site that is excluded ,  from the HNQ list.
The strange thing is that those MSE questions are not in the regular HNQ list.
How is this happening? Is there a separate check for HNQ and the HNQ feed?
Has the HNQ RSS feed for aye had MSE? (Can more three letter words be in that sentence?)
Is this a bug, or did I just discover a hidden feature?
