We’ve added a few more portals and their respective news feeds and, now that the news system has been live a few days we’ve updated the front-page algorithm to better reflect trending topics 
Previously we were using a more liberal scope to accommodate the (fewer) threads, but now that we have many more being posted on a daily basis we’ve brought in the original algo to better reflect the respective time-frames. The filter-by pages will use the old system for now, however we intend to update this when we when have added all news sources and these sub-pages get more threads too.
