This forum has a lot of beginners and people who are new to game development, it would be ethical if you remove your blog link or amend the terminology as quick as possible. This can cause misleading idea on C2, I'm sure you don't want to do this to beginner, it can cause snowballing effect.
Note on the "tile" terminology, I think it would be much helpful if you don't force the term that is accepted outside C2 onto the community, because it is fairly established here that "tile" is referenced to tile background and tilemaps. For "sprite", people would just call it animation or just sprite. Use of terminology would certainly change, if you found something confusing, you should be requesting for terminology amendment from Ashley, not to use them to make your point.
I agree with shinkan, experienced users might laugh at the mishap, but misleading beginners is a bigger concern. This is a serious suggestion, I'm not joking.
