There wasn't, but I took it as the average, which still seems low. Since I discovered HN, I've been nothing but impressed with the audience. I think the nature of the site is one of the reasons the topics and comments are of higher quality than other news aggregation sites.
Well over a decade ago, I was a regular reader of /. and I find that HN is reminiscent of those earlier days. After adding moderating and meta-moderating, the quality of /. suffered. I'm sure it wasn't moderation that actually brought about those problems and it had more to do with reaching a broader audience, but still it is unnerving to see my favorite forums gradually follow the same trajectories time and time again.
