@Edent Would this be a reasonable measure of success - if we reduced the impact to the same level as being posted to a popular news site?If so, then proposals I've seen to delay page preview generation /until a user views a post/ may help? Of course that now depends on what 'viewing a post' means - it would have to be /clicking/ on a post, not an automated feed, and caching the preview per instance will reduce impact compared to hackernews or similar... maybe?
