Regarding 2, I think the default setting (Popular) is to display comments as a function of karma and time since posting. As comments get old, newer comments float to the top even if the older ones have some positive karma. If some comment has very high karma, I guess it outweighs the time constraint and stays at the top.
… and the ageing function is tuned for Reddit traffic volumes, so on this site, everything ages too fast and can’t stay in popular for very long at all. Open source contributions to fix this are welcome.
