• There isn’t off the shelf software to run things like Reddit, and the work to make that happen is pretty staggering. That isn’t to say there isn’t frivolous spending there - I have no idea.

    Lemmy has been developed since 2019 and the software crumbled when network-wide users spiked into the ~75,000-ish monthly range when some vocal Reddit users sought greener pastures over the app/api issue last year. A lot of talented new developers contributed scalability fixes that were obvious to them (but not obvious to the main devs), and we now have the largest Lemmy server handling ~10,000 monthly users without crashing. The work that has gone into making Lemmy, an open-source Reddit alternative written in Rust (vroom vroom) handle the waning spike of Reddit users fleeing, was substantial. Look through the lemmy github issues discussions page and merged closed contributions/discussions for that journey. Those people were largely contributing time and expertise for nothing in return. Imagine paying a market rate to all of the people who contributed substantial time into the betterment of Lemmy. By the way, Reddit was open source: https://github.com/reddit-archive/reddit

    Takeaways so far: this is a hard problem, even today with faster software and hardware - and Lemmy needed a diverse set of contributors to get its largest server stable at 10k monthly and ~50k across the network.

    Reddit had 46,000,000 monthly active users in 2012, ~7 years after launch. Reddit has 330,000,000 monthly active users today. My guess is that Reddit employs a lot of smart software engineers that are needed to contribute solutions that allow the site to serve an ever-growing user count without major outages with new features rolled in. Meanwhile, the vast majority of Reddit users will never pay a thing to Reddit and it isn’t a good platform to deliver advertising through.

    My point: It is easy to gloss over the staggering amount of work, talent, and skill that goes into supporting a site that operates at this scale. Reddit is around the 10th largest site in the US (8th if you exclude search engines) and 12th globally excluding search engines.
