Thank you for drawing my attention to this issue, which I wasn't aware of.
This is most likely connected to GitHub Pages' recent upgrade to Jekyll 3.
I'll investigate this particular issue when I have time, but I'm no Jekyll or Ruby expert, so if anyone reads this, and think they can help, I'd appreciate it.

When I look at http://blog.ploeh.dk/rss.xml, the most recent article is linked like this:
<link>
http://blog.ploeh.dk/2016/02/12/types-properties-software-properties-for-the-advantage-state/
</link>
This URL seems to be perfectly reachable. It's not the URL you've reported, though.
The URL you've reported is present in the RSS feed, but in the <guid>
element; you can't expect this value to be a URL, let alone a valid URL.
The same goes for http://blog.ploeh.dk/atom.xml. The link is provided in a <link>
element:
<link rel="alternate"
type="text/html"
href="http://blog.ploeh.dk/2016/02/12/types-properties-software-properties-for-the-advantage-state/"/>
Again, the link you are reporting is the <id>
field, which you should treat as an opaque identifier - not as a URL.

Hum, you're right.
I'm using feedly to manage my subscriptions when on a browser. The subscription points to the right url, and the target xml is as you described it. However feedly seems to use the guid instead of the link, even for the link-sharing functionalities.
Seems like a bug on feedly side, not on your end, sorry for the disturbance, I should have checked the source directly instead of relying on what's provided on the interface.

Before contacting feedly to fill a bug report, I checked the RSS spec (as it seems that feedly only uses the RSS file for this blog), and contrary to what I expected, it seems that depending on the interpretation of this spec feedly's behavior can be correct.
http://cyber.law.harvard.edu/rss/rss.html#ltguidgtSubelementOfLtitemgt
If the guid element has an attribute named "isPermaLink" with a value of true, the reader may assume that it is a permalink to the item.
isPermaLink is optional, its default value is true.
I didn't know that, and it feels odd, but it's consistent with atom specs which states that ids must be valid, stable, rfc3987 IRI.
Learning things everyday. ^^'

Good research work 👍 I didn't know that.
It seems that the correct resolution to this issue would be to add the attribute isPermaLink="false"
to the guid
element. Do you agree?

Hi,
I think this should do the trick, according to the spec, however it's still a bit of guesswork hoping that feedly follows it. ^^'
In fine, it depends mostly on what you want to express in your feed, adding this would clearly show that you don't guarantee this guid to be a valid link.
from ploeh.github.com.
OK, the change is now live. It may take a while before it propagates through all caches.
from ploeh.github.com.
Tested, I confirm that feedly now uses the data from the link tag and not anymore the data from the guid tag, for both display and social share.

Sounds good. Thank you for providing feedback. Can we close this issue, then?
from ploeh.github.com.
Sure! Thanks for your time.
