"I caution against beginning or ending a quotation with ellipses."
-- Bill Walsh
Did you read the subtitle?
"For years, a subculture of teenage hobbyhorse enthusiasts flourished under the radar."
Can we stop the jousting match here? If this were a website for teenage hobbyhorse enthusiasts I'm sure it would be old news. But it's interesting to people who haven't heard of it before. It's OK for others to like things that you don't. There will always be some of that on Hacker News and the most polite thing we can do is leave others to their enjoyment.
