Blogging !== note-taking, but you could definitely make the argument that a blog post is semantically a public note.

Apple, Fox, Shell, Target...any of these generic words ring a bell?

I’m sure there was no malicious intent, and it’s very possible that these two products will coexist without any further issue.

But as evidenced in this very thread there is the potential for confusion, which is the whole point of trademarks, and the reason why I’d have an easier time incorporating “Apple Surfboards“ than I would “Apple Keyboards”.
