A new form of mailing list ?

The Ethereum blockchain support smart contract, therefore to interact with them you need to fill a "data form" in your transaction
Because you can fill in with the hexa you want (in any transaction), you can "write", and upload anything you want. The site etherscan.io can display the ASCII, for example here (it's written "Hi here") : https://rinkeby.etherscan.io/tx/0x00bfab09b0c950967b252c10f50ea0c2d65af39e1289feb7057805f12a3753bd

Not my code but here is a JavaScript client using the etherscan API : https://pastebin.com/8GfHAQQm

Howerer because it's expensive (the more data you upload the expensive it is) I guess people would talk on one of the ethereum test net (on rinkeby you can get a dozen of ether for free, enough to talk for a while) (ethereum or another one it doesn't matter)

I guess next generation of Internet puzzle (like CICADA3301) will be upload on blockchains instead of twitter

I found the concept "cool" therefore seeking for your feedback being not a cypherpunk
