I’m not entirely clear why primal hasn’t pushed harder on this from DAY ONE… but I suspect it has to do with shifting paradigms. WoT filtering (done right) requires some infrastructure (as we’ve discussed) and some additional work by the end user (configuring filters) in order to provide satisfactory results. In turn, this requires investors and developers to think differently about what is “important content” for each user … paradigm shifting takes time. That’s my take.
