Tophurioussaid: i'm willing to bet that they stopped doing news articles for TH because the news feed from last year is cluttered with mtx updates and barely any meaningful updates.
There are even more SGS sales News this year - you got one every week, but that's only in the RSOF.
Jagex talked about TH promotions in vidoes together with other game updates now. Perhaps their marketing team found TH is more effective to be shown on vids. Different audience with different sizes and preferences.
