Okay, we need to have a talk. You should check your grammar and capitalization, or you shouldn't contribute quotes. I have had several perfect runs ruined by random capitalization and off-putting grammar. First, capitalize nouns and names only, unless you are directly quoting a textual work that does it. Second, use Oxford commas on the last item in a list. Third, do not capitalize a word that follows a colon or a semicolon; they just break a sentence up. Periods: use them to end a sentence.
The mistakes teach you not to predict what's coming next, but to simply type exactly what's in front of you. Which will help your speed in the long run.
Generally, the first word following the colon should be lower-cased if the words after the colon form a dependent clause. If the following phrase is a complete (independent) clause, you may choose to capitalize it or not.
This is one of my favourite quotes on this site! People need to be more courteous to other users when posting quotes. No one is so busy that they can't take a minute to edit their quote prior to submitting it. If you feel you have something important enough to share with others, it should be important enough for you to spend a minute editing it!
