The "supermoon" may look slightly larger than the moon normally looks when it's close to the earth (i.e. every two weeks), but not significantly. In particular, it pales in comparison to the psychological effect of viewing the moon low in the sky (when it looks larger, even though it's actually further away) vs high in the sky (when it looks smaller, even though it's actually closer).
But there's still no reason it should be in the news: regular people wouldn't even notice if it wasn't pointed out to them, and astronomers know it's just a cyclical thing that doesn't mean anything. Imagine if, every spring, the news was full of breathless reports of the upcoming "supersun" which would be much brighter than the "winter sun" and which would stay in the sky for hours longer than the winter sun. That's pretty much the level of amazement we're talking about.
...and in other news, Generalissimo Francisco Franco is still dead and water is still wet.
