Idiots that excluded punctuation

Jimmy: Come on, we have to cook Adam!!
Adam: Are you implying that you're going to cook me?

Proper Sentence
Jimmy: Come on, we have to cook, Adam!!
Adam: I'm coming downstairs now!

Punctuation is a key part of everyday writing. Otherwise the phrase "I helped my Uncle, Jack, off a horse" becomes "I helped my Uncle Jack off a horse". See what I mean?

Often times puncuation is critically lacking online. Not to mention spelling.

Punctuation consists of marks that improve sentence structure and overall grammar. (!.';: etc.) It is a theory that has failed to reach many textaholics and most of the internet. (See those periods? those are part of punctuation!)
Texter1: Zomgwtfbbq did you just say
Texter2:Wait, is that a question? There is no punctuation, that could be a declarative sentence.
Texter1: Wtf did you just say
Texter2: Still waiting....
