Grammar? Punctuation? Why Not Just Guess?!

I was curious this morning, while I was doing my job as a Technical Writer (and Analyst, and Tester, and Instructional Designer, and Documentation Specialist, and Graphic Designer), about the rules for capitalization after a colon.

I was shocked to find out, that THERE IS NO CLEAR CUT RULE FOR THIS.

So I guess if you want to capitalize after a colon, go ahead. If not, then dont.

How many years has this stupid language been around… .AND WE STILL DONT KNOW YET?!?

WTF?!?! Kill me now!
