It doesn't matter if it is a good blog. Any time a blog links to another blog is blogspam. Blogspam is fine in some contexts — it's a great way to share articles between communities that would otherwise be unconnected — but it doesn't belong on a link aggregator like Hacker News. It's mandatory to always link to the original article.
