I think that reminding people to read the guidelines does not necessarily mean that HN is becoming bad. I incur sometimes in posts that do not follow the guidelines and get a lot of downvotes. Half the time they are from new users that maybe do not even know about those guidelines, so maybe they do not even understand why they are getting downvoted. Of course they can learn it the hard way, but reading the guidelines is a lot faster and wastes less of everybody's time. In the same way there are some posts that are not appropriate to this community. In the last days I did not find many interesting posts in the first page, but that's just my opinion and the community as a whole decides what goes up or not. Nonetheless some days ago I even found a link to thisisphotobomb.com (a websites of the cheesburger network, like the lolcats) and this is clearly against the guidelines. Again, there are the voting system and the flagging system, but it wastes less of everybody's time just to know the guidelines and it's better not to pollute the new posts section. In each of these cases I think "you should read the guidelines", but don't write it because it's against them. But the fact that lately I've been thinking it more often, means that a kind reminder is not totally out of place. Does this all mean that HN is becoming bad? I don't think so. It just means that we have guidelines we care about because they made HN a place we all like.
