I am not saying all of TC is irrelevant. We have our share of irrelevant stuff from other sites too. But on average we get 3-4 stories from TC posted here on HN, stuff like twitter going down (every freaking time, how often does it happen?), facebook going down for 5 minutes, rackspace going down (in itself is relevant news, but from TC the news is the internet went down because TC is hosted on rackspace). If this much crap was posted from any other website, they would have been blocked without any debate whatsoever. There is a reason people subscribe to rss feed, why would I come to HN to see one blog hogging the whole site? Which is why I suggest either a hard cap on number of subs per domain per day or give users the option to block out certain domain so that they don't see it in their HN. I don't think it is an unreasonable or very difficult request to implement.
