One test I've used to check relevancy is to follow our posts on twitter. A lot of our posts are aggregated on various HN twitter feeds. Some, more than others.

One test I've used to check relevancy is to follow our posts on twitter. A lot of our posts are aggregated on various HN twitter feeds. Some, more than others. I've been using this to determine the quality of the post and understand what various HN tweeters find valuable. There's so many great posts on HN that get zero comments or up-votes. I'm convinced there are a small number of posts that get enough momentum from a very select group of voters, and once these posts are "blessed" so-to-speak, they then get some frontpage exposure - which gets them to some valid threshold allowing the community give it further boosting.
