Both of those would probably be best described as "alternate" links.
The second one in particular is what "alternate" was intended to be
used for. However, RFC 4287 contains the following:
o atom:entry elements MUST NOT contain more than one atom:link
element with a rel attribute value of "alternate" that has the
same combination of type and hreflang attribute values.
So you couldn't keep both as "alternate" links. In my opinion, you
should use the second one (the longer lasting one) only, and omit the
first (which is going to become invalid as soon as the entry falls
off the page anyway -- anyone who used it to get to your page and
bookmarked it, and anyone who follows it from a cached copy of your
feed isn't going to be able to find the entry without a lot of
needless digging through your archives). You should have a link to
http://www.cafeconleche.org/ at the feed level. While that won't
link directly to that entry, it'll get people to it as long as it's
on that page.
