From the article:
"Beehaw is relatively new and relatively small at the moment, but it’s one of the closest approximations of what Reddit is that you’re going to find, and well worth investigating as a Reddit replacement. The interface even looks a lot like Reddit, albeit without a lot of the on-screen features and furniture that build up over almost two decades of operation.
Have a read of the Beehaw mission statement and you’ll see the platform is committed to avoiding the “hate speech” and “disinformation” that’s prevalent elsewhere. The communities available right now cover everything from neurodivergence and people of color to literature and gardening, so you’re sure to find something of interest here."
Slashdot is the pre-cursor to digg and reddit in a lot of ways. It’s problem was people wanted freedom to create communities and submit posts whereas /. wanted to be able to control what appeared on their site. Both digg and reddit were responses to that aspect of slashdot. That, and their moderation system tried to be democratic, sharing the load amongst users, rather than installing mods (which ultimately was a failure imo).
