    Reddit on the Bitcoin blockchain Test
    TODO understand this part: 
    The "Address" you see above is more than a bitcoin address? For example, the web address to this 

reddit thread is: https://www.reddit.com/r/Bitcoin/comments/3cdxep/reddit_on_the_blockchain_test/

Which converts to the bitcoin address of:
12uPLj6PSz6ULnZi1jXo7Ch1Je1SuqxRcE

How? Because any text, like a web address, can be converted into a bitcoin address.

Coinbase message are messages that only miners can embed in the blockchain.
As such most of them tend to be boring ads for mining pools, but there are a few exceptions, especially in the early days.
The Horrible Horrendous Terrible Tremendous Mining Pool inscribed a few cute Coinbase messages during their operation in 2012-2013.
Many of their messages also mention SockThing, which was part of their mining infrastructure:
block 229417 (2013-04-03) has a cute sword ASCII art: 
./SockThing/HHTT/o()xxxx[{::::::::::::::::::::::::::::::::::>
Starting from their very first ASCII transaction on block 197602 (2012-09-07), there is what seems to be a poem spread across several transactions. Some of the lines are repeated, presumably because they didn't update the current line to a new line and so mined the same thing multiple times:
I am a pretty princess
covered in mud and blood
water with stuff in it
like everything else that wiggles or jiggles
screaming might not be your waY
see no reason to operate otherwise since
came into the world naked, wet and screaming
but silence will never be mine
until I am dead
but the smell will also give that away
gather all my things
load them in a big boat
airlift that to Kansas
and light it on fire
drop it from 7,000 feet
then railgun my corpse straight down
The sentences are not very coherent together, perhaps this is because lines were chosen by different miners one at a time.
Bitcoin addresses are by convention expressed in Base58, which is a human readable binary-to-text encoding invented by Bitcoin. It is a bit like Base64, but obsessed with eliminating characters that look like one another in popular but stupid fonts like capital "I" and lower case ell "l".
This seems to be one of the earliest strategies used to encode messages.
The generated text is however rather obfuscated by the limitations of Base58.
The following transactions contain base58 encoded messages on addresses:
This website used to allow embedding text messages with OP_RETURN, here's an archive from 2015: web.archive.org/web/20150718052659/http://eternitywall.it/
As of January 2024, it seems to read-only mode, where it simply indexes matching transactions that were made via other means: web.archive.org/web/20230929075331/https://eternitywall.it/
There were 3191 hits for the search term:

EW May our friendship endure, signed by hg, kty, wjj, and xyz.
no doubt initials of 4 Chinesepeople. A blood brother oath comes to mind, akin to the Oath of the Peach Garden. Will these four be the ones to take down the evil dictator Xi Jinping?
The very first message gives away the name of what we assume is a web-based upload system, "EW" being its advertisement signature added to every message.

TODO what is up with that?
In that first trasaction the quotes appear as part of a Multisig output script.
