These tech forums have not suffered.
*espec.ws
*remont-aud.net
*elektrotanya.com
*eserviceinfo.com
*forum-monitor.net.ru
*vlab.su
*elvikom.pl
*These names are examples of value‑structured communities -- the specific sites don’t matter. What matters is the participation model they use.
Some are even growing as English speaking crowd tickles in, more and more posts and replies within posts are seen in English.
All these boards have historically been hard to get into:
1) Entry tests are required.
2) For full access participation is required.
3) VIP and special paid accounts still don't get everything, participation for special members is required.
4) Proper participation requires having expensive tools, such as oscilloscopes, infra red soldering stations, EC programmers, microscopes.
This weeds out the newbs and passerby's, who do not provide any value to boards.
Basically, these are not quick boards where you can pop-in, get what you want, and then pop-out. These boards require you to participate and contribute, provide advice, take time reading BIOS dumps, upload files, etc. There is a value in a forum onto which you can login, post your measurements and problem, and get answer within hours. Professional repair technicians use these forums, and they have become a livelihood for many tech repair shops, without such tech support I don't believe it is possible to proficiently diagnose and repair modern electronics.
VALUE. Is what matters.
There is great VALUE in a forum which is full of professionals.
There is great VALUE in a forum which has FREE access to proper repair materials, boardviews, schematics, BIOS dumps, EC dumps, NVM and OTP regions, VRM compatibility cross refence charts, etc.
Forums that provide VALUE don't die.
There is another great forum, also technical, but in a different format 4pda.to/forum/ This forum has also not experienced any slow downs. Format is a bit different, forum is about devices. Let's say greatest cheap peoples TV everyone can afford, which changes year to year. A specific platform of a TV. USB testers from aliexpress. NAND programmers. Specific NAND programmer. Etc. VALUE in this forum comes from great knowledge on practically any device you can think of, you'd find firmware, advice, problems and solutions, modifications, hacks.
What has changed? The western segment of forums.
Google began giving trash content sometime around 2014 - 2016. SEO optimization was at it's highest. Less and less hits from forums, more and more hits from commercial sites who wrote their copy pasted and SEO optimized garbage articles. Then COVID and watch-TV at home time around 2020 - late 2021. Then in 2023 Ai went mainstream and viral. Western segment of forums has taken a major hit. Eastern segment forums have stayed up and even grown, because of user base model which weeds out people who'd leave and won't participate -- forum members who do not provide VALUE. Typical western man or woman see value in asking Ai, instead of posting in forums. Forums are not providing enough value, that's the reason for the slow-down or dying off.
Basically, people who used to ask beginner level questions now ask Ai.
People who used to give beginner answers now don't bother.
People who used to hang out casually now scroll TikTok.
And people who still want real technical help have moved on elsewhere. I'm guessing to closed communities with credit systems and [spoil=] BB tags. Where there is obvious VALUE to be around real experts.
P.S. It's important to note that my analysis is about community structure, not monetization. Advertising models, CPM, SEO, and revenue pressures are a completely different domain. They affect forum owners, not forum users. The slowdown we're discussing is caused by user behavior, not by advertising economics. So even if CPM dropped to zero or rose to $500, the participation dynamics I described would remain unchanged. Forums that rely on advertising behave differently from forums that rely on expertise. The eastern forums I listed do not depend on CPM at all, which is why they were unaffected by Ai, SEO, and social media. Their survival mechanism is structural. That's why they are relevant examples in a discussion about user participation. Also, geographic location and language is absolutely irrelevant. What matters is structure of community.
P.S.S. Communities that have weak structure get affected, and the weaker the structure the more impactful they get affected.
