The value of the blog post is negatively correlated to how good the site looks. Mailing list? Sponsors? Fancy Title? Garbage. Raw HTML dumped on a .xyz domain, Gold!
That's a negative correlation signal for me (as are all the other weird TLDs that I have not seen besides SEO spam results and perhaps the occasional HN submission.) On the other hand, .com, .net, and .org are a positive signal.
