+I think we should agree on an HTML attribute for pointing to the Nostr representation of a document/URL on the Web. We could use the existing one for link relations for example. Something like:
+
+```html
+<link rel="alternate" type="application/nostr+json"
+      href="nostr:naddr1qvzqqqr4..."
+      title="This article on Nostr" />
+```
+
+This would be useful in multiple ways:
+
+1. Existing Web publications can retroactively create Nostr versions of their content and easily link the Nostr articles on all of their existing article pages.
+2. Nostr clients, when fetching meta/preview information for a URL that is linked in a note, can detect that there's a Nostr representation of the content, and then render it in Nostr-native ways (whatever that may be depending on the client)
+3. User agents, usually a browser or browser extension, when opening a URL on the Web, can offer opening the alternative representation of a page in a Nostr client. And/or they could offer to follow the author's pubkey on Nostr. And/or they could offer to zap the content.
+4. When publishing a new article on Nostr, authors can share their preferred Web URL everywhere, without having to consider if the recipients' clients support Nostr IDs and content or not. This makes it easy for the reader to share the author's preferred Web URL on any medium, instead of sharing a link to whatever their own Nostr client prefers (usually its own Web UI).

+<p>
+  This week, it finally happened: I still had a Lightning channel open with a
+  node that hadn't been online for the better part of a year now, so I decided
+  to close the channel unilaterally. But force-closing a channel means you have
+  to broadcast the latest commitment transaction, the pre-set fee of which was
+  only ~1 sat/vB for this one.
+</p>
+<p>
+  With LND, if the channel is created as an <a
+    href="https://lightning.engineering/posts/2021-01-28-lnd-v0.12/"
+    rel="noopener noreferrer"
+  >anchor channel</a> (by default only since version 0.12), then the commitment
+  transaction contains small extra outputs (currently 330 sats), which let
+  either channel partner spend one of them into a child transaction that can be
+  created with higher fees to pay for the parent transaction (CPFP). LND even
+  has a built-in command for that: <code>lncli wallet bumpclosefee</code>
+</p>
+<p>
+  However, this channel was created in the old-school way, and was thus stuck
+  with its low fee. In fact, even the local bitcoin node refused to accept the
+  transaction into its own mempool, so the bitcoin p2p network didn't even know
+  it existed. So how do we get out of this pickle?

+</h2>
+<p>
+  Enter the <a
+    href="https://mempool.space/accelerator"
+    rel="noopener noreferrer"
+  >mempool.space Accelerator</a>. It is essentially an automated way to create
+  agreements with various mining pools to mine your low-fee transaction in
+  exchange for an out-of-band payment. Mempool.space coordinates these
+  agreements and out-of-band payments with miners and gets a share from the
+  overall fee for that.
+</p>
+<p>
+  Now, if you're in the same situation as I was, you might search for the ID of
+  your closing transaction and find that mempool.space cannot find it. Remember
+  how the local bitcoin node (with mostly default settings) didn't accept it in
+  the first place?

+</h3>
+<p>In your <code>bitcoin.conf</code>, add the following line:</p>
+<pre><code>minrelaytxfee=0</code></pre><p>
+  This sets the minimum fee to 0, meaning it will accept and broadcast your
+  transactions, no matter how low the fee is. Restart <code>bitcoind</code> and
+  wait a little bit. LND will retry broadcasting the closing transaction every
+  minute or so until it succeeds. At some point you should be able to find it on
+  mempool.space.

+</h3>
+<p>
+  Once you can see the transaction on <a
+    href="https://mempool.space"
+    rel="noopener noreferrer"
+  >mempool.space</a>, you can just click the "Accelerate" button next to the
+  ETA. This will bring you to a page that shows you the estimated share of
+  miners that will include your transaction in their blocks, as well as some
+  acceleration fee options for various transaction fee levels, which you can pay
+  for via the Lightning Network, of course.
+</p>
+<p>
+  If you haven't looked into this service before (which I had), then the fees
+  might be a bit of a surprise to you. This thing is <strong>not</strong> cheap!
+  Bumping my fee from 1 sat/vB to <del>9 sats/vB cost a whopping 51,500 sats
+    (</del>31 USD that day). Bumping it higher only seemed to add the difference
+  in the transaction fee itself, so the service seems to have cost a flat 50K
+  sats at the time.
+</p>
+<p>
+  Unfortunately, this channel wasn't particularly large, so the acceleration fee
+  amounted to ~9% of my remaining channel balance. But 91% of something is
+  better than 100% of nothing, so I actually felt pretty good about it.
+</p>
+<p>Next, you will see something like this:</p>
+<p>
+  <img
+    src="https://image.nostr.build/76151cc2ae06a93a8fcd97102bf4fa63541f8f3bd19800b96ff1070c9450945c.png"
+    alt="Screenshot of an accelerated transaction on mempool.space"
+  />
+</p>
+<p>
+  Time to lean back and let the miners work for you. In my case, the ETA was
+  eerily precise. It told me that it would take ~56 minutes to confirm the
+  transaction, and almost exactly an hour later it was mined.
+</p>

+      >
+      </path>
+    </svg></a>3. Wait
+</h3>
+<p>
+  Now that our transaction is confirmed, our channel is not closed immediately,
+  of course. The <a
+    href="https://docs.lightning.engineering/the-lightning-network/multihop-payments/hash-time-lock-contract-htlc"
+    rel="noopener noreferrer"
+  >time lock of the HTLC</a> protects our channel partner from us broadcasting
+  an old channel state in which our balance might be higher than in the latest
+  state.
+</p>
+<p>
+  In my case, it was set to 144 blocks, i.e. ~24 hours. So I checked back the
+  next day, et voilá: channel closed and balance restored. 🥳
