Suggest me a community app to discuss software tech stuff.

Have tried a few apps but there’s too much clutter.

• Discord: Too many channels, unorganized & cluttered
• Reddit: Used it long time back but not so good for productive discussions
• Twitter: Frontend folks discussing same stuff over and over.
• Slack: Haven’t tried yet. Do have have public communities there?
• LinkedIn: Not interested in illusions created by fancy tech jargons to outscore other professionals.
• Grapevine: Not ideal for my use-case.

Is there any genuine app you know that can enable me to discuss tech stuff in software engineering?
