Why Internet discussion forums are emptying out

The twilight of discussion forums: why deep-discussion spaces are emptying

A professional looks for a specific piece of information about a regulatory change. Ten years ago, he would open a specialized forum, read three pages of threads and extract the consensus. Today he types the same question into ChatGPT and gets an answer in five seconds. The scene repeats itself millions of times and helps explain why forums that were once benchmarks — such as those dedicated to economics and investment — are losing traction at an accelerating rate.

AI as a substitute for collective consultation

The first blow comes from generative artificial intelligence. Faced with the time cost of filtering through 30% useful contributions, another 30% ramblings and 40% militant noise, the average user prefers an assistant that gives them the answer packaged. Immediacy kills deliberation. New generations, moreover, have grown up with TikTok, Instagram and 280-character messages: patience to read and write a 40-line analysis is scarce. With each passing year, the user base capable of reading comprehension of long texts shrinks, according to several analyses.

Fewer incentives to contribute, more noise

But not everything is the fault of AI. The spaces themselves have degraded. The signal-to-noise ratio has plummeted: five useful contributions for every twenty personal fights. Invasive advertising, the requirement to register to read content and the feeling that quality threads are increasingly rare scare off the occasional user. Those who stay tend to be the most radicalized — politically or in their obsessions — which drives the rest away. The result is an echo chamber that feeds back on itself: fewer normal people enter, less interesting content is generated, and the exodus accelerates.

The surprising data: stable activity, declining engagement

Paradoxically, some indicators do not show a catastrophic drop in the number of active accounts. What has collapsed is intensity: before, a thread needed a hundred replies to appear in trending; now it achieves that with thirty or forty. New posts pages have shrunk from three to one. That is, the hard core is still there, but it produces less and attracts less participation. The forum has not died, it has shrunk until it has become almost invisible to the general public. And with competition from AI and social networks, the trend only points to worse.
