It was more of an idea than an ongoing project.  I think anyone (with the right technical capabilities) could set up a website with a human readable interface that reads messages from ETH or DOGE transactions similar to memo.cash.  The hard part would be getting enough users to communicate this way instead of using Twitter.

But if enough people started "tweeting" this way, it would be an easy way for those who want censorship to use sites that censor to their preference and those who don't want any censorship, to use sites that censor to their preference.
