This is my first real reading of Daily Kos, but I already hate all the identical subject lines. It makes is impossible to scan the subjects and see which comments you would like to read. This especially makes dynamic minimal a useless mode and nested useless on larger stories.
What a fucking terrible idea.
Poll inside is a choice between all comments have defaults (Kos-style), non-top level comments (Slashdot-style), no comments have defeault subjects (Kuro5hin-style).
