Yes, this would be a good idea. The forum is still in progress, so we can decide together, what categories to add.
Here are my additional suggestions:
General Discussion: A catchall for all things on Sensor.Community.
How-To General How-To small wikis.
Meta: Ongoing discussion about this community forum, its organization, how it works, and how we can continue to improve it.
Technical Discussions: Anything relating to technical discussions goes here, like sensors, api, data formats…
I also like your scientific category.
Scientific: Analysis, evaluations and other scientific discussions
Let’s see what other will suggest.
