In English, capitalization applies to,
1) First word
2) Proper noun
Some new rules,
When a Proper Noun has more than one word, use capitalization
for both the words, just like CamelCase
When a verb has more than one word, captalize the second word.
When describing attribtutes, use hyphenation.
When a Verb is used as a noun, capitalize it.
When you feel like, emphasizing a word, capitalize it.
When the word really needs to stand out, CAPITALIZE EVERYTHING.
