HN should have descriptive subtitles though, the title of this piece only makes sense once you know the context, and if browser UA isn't of interest then that's wasting clicks. "An analysis and history of web browser UA strings" seems like a good subtitle to me. Also, if someone takes a conversation in a direction in a forum that you don't want to follow then best response is usually 'don't follow'.
