I propose a ban on such posts in the future. HN is becoming Reddit. If you really want to point out all the cool stuff in Google Search, create a list and submit that list.
Interesting. I think I like the idea of having different sites with different granularities. HN could be a site that occasionally has a post saying, "Hey, there now exists a subreddit for this," and Reddit could have articles saying, "OMG, pg just tweeted about a sandwich!" And since news.rc is so easy to run, it should be easy to throw another news server (wow, remember when that phrase meant something else?) up there (except for the OpenId integration, that is) for each internal node in the LOD structure of sites.
