There are some topics on popular blogs which the readers will react to as cats react to catnip. It's not a pretty sight. One such topic is advice on PC hardware--Kevin Drum asked for comment on a report that some Mac user replaced the computer hard drive 3 times in 2.5 years.
His commentators rose to the topic, notably competing for the title of whose first computer was the oldest and smallest. Not sure why, though it's probably the same logic why us geezers talk about how hard our life was compared to today.
