The author seems to have assumed that readers are going to know that he's talking about NPM and JavaScript, and that "lockfiles" are an NPM-specific feature (to me, it means something completely different).

Perhaps that's a valid assumption for readers of his blog, but once it appears here there are going to be a lot of readers who don't have the context to know what it's about.

Can an "NPM" tag be added to the subject of this post? More generally, I encourage authors to include a bit more context at the top of an article.
