Spazless (proposed)

Spazless is a proposed nonprofit Reddit alternative that would operate similarly to Reddit but as a nonprofit that funnels revenue back to communities and moderators. The idea emerged during a major Reddit protest in 2023 when 93% of subreddits went dark to protest API pricing changes that would kill third-party apps like Apollo. The domain was registered as a conceptual project to capitalize on user discontent.

Threadsby Mark Zuckerberg

Threads is Meta's text-based social network launched in July 2023, reaching 100 million users in its first week by leveraging Instagram's existing user base. The platform positioned itself as a kinder, more moderated alternative to Twitter, with Meta's 20 years of experience managing abuse and spam. Early traction shows potential to disrupt Twitter despite questions about long-term retention and whether it can sustain growth beyond early adopters.

Redditby Steve Huffman, Alexis Ohanian

Reddit was founded by Steve Huffman and Alexis Ohanian in 2005 after being accepted into Y Combinator's first batch, inspired by Paul Graham's observation of delicious.com's popular links feature. The founders bootstrapped early growth by creating 30 fake accounts with different personalities to generate initial content and conversation, solving the chicken-and-egg problem of community platforms. After 16 months, they sold to Condé Nast for $10 million, and later bought it back; the platform has since grown to become one of the top 10 most visited websites globally despite remaining unprofitable.
