Maybe. Probably. But after being here for 2 1/2 years, and getting in the top 20 on the leader board, and having replied to so many people, I thought it courteous to let them know.
If the acculturated core of users are overwhelmed by an influx that is larger in number than the core, it seems to me that is when a culture shift happens. I think the first thing many noobs (myself included at one time) think when they see HN is "oh, reddit for tech stuff and startups!" so I think that is where the revolution is taking us.
