[TO HN WEB DESIGNER] Please remove new black line from top

The black line appears when someone notable in the community passes away.

In this case http://www.media.mit.edu/people/in-memory/papert

I would guess it's there because of https://news.ycombinator.com/item?id=12201810

If you really want to contact the web designer, there is a 'contact' link in the footer. But as others have noted it's because somebody notable passed away.

I thought it was a "mourning" thing and was trying to find out who, known to the HN demographic, had died.

It's it not that?

Ha, and I thought Papert deserved more than a 5-pixel tall black line :-)
