Guide to Finding Lemmy Communities (Subreddits)

How To Find Lemmy Communities

This article will show reddit refugees how to easily search-for and subscribe-to to popular lemmy subreddits communities across all lemmy instances.

tl;dr use the Lemmy Community Browser https://browse.feddit.de/ Intro

Lemmy is a federated reddit alternative that started in 2019. Thanks to funding from NLNet, Open Collective, Patreon, and Librapay, the project has two full-time developers.

Unlike Reddit, all of Lemmy's code is open-source under the AGPL.

Context

In 2008, Reddit launched an API that allowed third-party clients to use Reddit. This API has been free for 14 years.

In April 2023, Reddit announced that they would begin charging for use of their API, starting just 3-months later. This made headlines when one developer calculated that reddit's proposed fee structure would cost them $20 million per year. As a result, most popular reddit apps including Apollo, RIF, ReddPlanet, and Sync are all shutting down in July.

In protest, hundreds thousands of subreddits are participating in a reddit blackout on June 12th.

At the time of writing, all the apps still work and protest hasn't even started yet, but already thousands of reddit refugees have flocked to lemmy -- at a rate of about 2,000 new users per day. And because

WordPress Multisite on the Darknet (Mercator .onion alias)

How to use a .onion with Wordpress Multisite

This article will describe how to point a .onion domain at your existing wordpress sites (on wordpress multisite) so that your website will be accessible both on the clearnet and directly on the darknet via a .onion domain.

Intro

There are numerous security benefits for why millions of people use tor every day. Besides the obvious privacy benefits for journalists, activists, cancer patients, etc -- Tor has a fundamentally different approach to encryption (read: it's more secure).

Instead of using the untrustworthy X.509 PKI model, all connections to a v3 .onion address is made to a single pinned certificate that is directly correlated to the domain itself (the domain is just a hash of the public key + some metadata).

Moreover, some of the most secure operating systems send all the user's Internet traffic through the Tor network -- for the ultimate data security & privacy of its users.

In short, your users are much safer communicating to your site using a .onion domain than its clearnet domain.

For all these reasons, I wanted to make all my wordpress sites directly available to tor users. Unfortunately, I found that it's not especially easy to point a .onion domain at

This website is now accessible on the darknet. And how!

Why

Fun fact: the most popular website on the darknet is facebook. There are hundreds of other popular sites on the darknet, including debian, the CIA, the NYT, the BBC, ProPublica, and--now--michaelaltfield.net.

All of these organizations chose to make their websites available over .onion addresses so their website will be accessible from millions of daily tor users without leaving the darknet. Besides the obvious privacy benefits for journalists, activists, cancer patients, etc -- Tor has a fundamentally different approach to encryption (read: it's more secure).
