Me too, but this one does: the far right link. I had to click most of the links on the top to figure that out, though.

Ah - good call. I totally missed that link.

Me too, so what is best practice?

I put together a simple layout for my company's blog and made this link very explicit specific, see: http://blog.vidoyen.com

Is that more in line with a blog reader would generally expect? I'm genuinely curious, because I've seen variants of this comment time and time again on HN.

My personal preference is for the top-left logo to always bring a user back to the domain's top-level ignoring any sub-domains, though I'm not sure that could be considered best-practice.

This approach works for me though, because I find most company-blogs to have a much lower volume of published content than a website whose primary function is that of a blog. In most cases, I've wound up on the site from a direct-link to whatever blog post I'm reading. If what I've read in that post is interesting, I'm probably going to want to check out the product or service they're selling before reading any more of their company blog.

Your site would actually make it pretty easy:

Have the logo redirect to your homepage. Have the 'Blog' go to the blog feed.

Logos that don't go to the homepage drive me batty.

I think we can surmise Instagram is not going to change the name of their new product just because this company wrote a blog post.

They will need to compel Instagram into doing so.
