RSS feed does not work

I added feed.xml to the root of my blog site, https://www.bododiehn.net/hello-world
I added the link https://www.bododiehn.net/feed.xml in “RSS” of the Primary Widget Area, telling it to show 10 items with content, author and date.
Here’s feed.xml which btw was validated as ok by feedvalidator.com :

<?xml version=”1.0″ ?>
<rss version=”2.0″>

<channel>

<title>Food for Thought</title>
<description>Unpopular Views on Politics, Science, and Literature</description>
<link>https://boddiehn.net/hello-world</link&gt;

</channel>

</rss>

But when I fire up Google Reader and subscribe, “Food for Thought has no items” comes up. I do in fact have several items on the blog site, as you’ll be able to see.

I am stymied.
