This happens almost 100% of the time with product updates. You are taken to a page that says "We have released version 3.1.5 of Gizmo. Download it here." with not even a hint of what Gizmo is.
Updates and bugreports are two communications I specifically had in mind when writing my "Tell me what the fuck it is EVERY GODDAMNED TIME YOU COMMUNICATE ABOUT THE PRODUCT" above. Major peeve.
Yeah, especially if you think your blog post will get submitted to HN or reddit or TechCrunch... assume that nobody knows what your company does! Those that do will just skip over it, and those of us that don't will now know and everyone's happy.
It gives me a nagging feeling that I am completely out of touch with HN, too.
The way moderators edit headlines doesn't help this at all.
