Thank you for these interesting additions @zoneboy!

Displaying and filtering tags will indeed greatly benefit the filtering of interesting discussions for the user. It was already on the to do list and can be expected in a few days. Points and rankings are interesting as well indeed. I will definitely keep an eye on the development of the SMT as this would be a great use case of those tokens.

I must say I am also intrigued by the idea of gathering (spatial) statistics about the different discussions but asking such personal details can indeed be discouraging as @syedumair already mentioned. Perhaps in combination with the point/SMT system it can be incentivised.
