At the beginning of the community, we created many specific groups for all kinds of topics: 5G, 3G, LTE, Core, Transport, Devices, Open RAN, and so on.
Each expert in each area joined the group(s) they wanted.
Over time, however, we realized this was a bad practice.
Let’s explain with an example:
- A member of the “5G-NR” group asked us to create another group specifically for “Private Networks”.
- The group was then created, and besides the member who requested it, other people joined. The specific discussion on “Private Networks” began.
- Soon, a member asked about the best CPE to use and if anyone had any references. To solve this, everyone joined the “Devices” group and got help from the experts there.
- The discussion resumed in the “Private Networks” group. But in another conversation, a question arose about Transport and Core configurations. To resolve this, everyone joined the “Transport” group and the “Core” Experts group. The question was answered, and they returned to the “Private Networks” group.
- Everything was fine until another question came up: how to off-load from 5G-NR to “Wi-Fi”? Again, everyone joined the Wi-Fi Experts group, got their question answered, and returned to the “Private Networks” group.
Well, we could continue with the analogy, but you probably see what happens with many groups, each for a specific topic (AI, Machine Learning, Visualization, Tools etc.).
We lose the whole concept of community, and the division creates more division.
That’s why we believe everyone should participate in a single group, a single place where each expert can contribute and also learn from others’ contributions.
If you’re still not convinced, try to remember how search engines were in the early 90s… they had several divisions - categories - for specific searches.
And remember also what eventually happened to all of them.
