So something to always watch out for is those pesky trademarks that people think should be lowercased but are--as of yet--still uppercase (brand-name). A couple of these I've recently noticed more, and some have been around for a while. The more a trademark is used in printed English, the more chance it has of becoming public domain and the standard term for the item it's referring to. This is so much the case that Xerox has launched huge ad campaigns in the past to try to get the public to say "photocopy" instead of "Xerox."
The following words are trademarked and should be capitalized in manuscripts:
Dumpster (looks weird, right?)
Sheetrock (another one that just looks weird)
World Wide Web (this one is particularly garish, although, thank heavens, Chicago, in its latest iteration has conceded to use "website"; hallelujah!)
Realtor (the third unnatural-looking trademark; feels like it should be lowercase)
Google (although a lot of editors will use "google" lowercase as the verb, while keeping the company/etc. uppercase)
App (Amazon and Apple are in a lawsuit about this very thing right now: whether "app" is an Apple trademark; the more the term is used as a generic abbreviation for "application," the less of a case Apple has)
