Honestly speaking, I did not expect this level of traffic on the site, there was a slowdown in the mail sending service, it is fixed now, please try again.

Looks like it might still be struggling with the HN hug. I tried it, I gave it three easy topics to use, it understood them and tried to produce the web page, but it still says “Videos: 0” for all three groups.

You can still get your fix in quick enough to benefit from some of this traffic spike, go for it! Good luck.
