The Microsoft Office paperclip assistant notices that you appear to be writing unsubstantiated nonsense... and asks would like to turn on all-caps (caps lock). It is so often the case that on the Internet, the all-caps shouting of enthusiasts occurs in direct opposition to the amount of support that those statements have. Of course, everyone gets excited sometimes. But beware in particular of entire paragraphs written in ALL-CAPS! Especially if they are followed by a wild series of exclamation marks.
