CAPS is an integral part of society. It denotes implied emphasis for what is being stated. Take the following example:
Robin: Holy rusted metal, Batman!
vs.
Robin: HOLY RUSTED METAL, BATMAN!
White in the first statement there is a sense of impressed Robin by the event at hand, the second statement clearly shows how blown away he is in relation to the current situation.
Example 2:
When someone joins a server you're excited to see...
Honored Droog: HEY! What's up?
Mistaken Ranked Member: caps, please.
See the fear in the correcting fellow's speech? They are so afraid to speak up they can't even summon an uppercase letter to start their misguided rebuke.
Now, I understand the confusion people have between CAPS and SPAM, but let me clear it up for you with a bit of low-down funk:
SPAM = Does not contribute to the conversation or thread at hand.
CAPS = May or may not contribute based on usage.
Generally if CAPS is combined with SPAM, then there's a problem. This is where most of the CAPS confusion stems from. Previous associations with CAPS-laden SPAM has led people to shun the former altogether.
Random Droog: OMG ROFLWAFFLE LOLLERSKATES HAVE YOU SEEN MY NEW WEBSITE!!!!
Minecraft Middle Earth
...is considered SPAM because of the content. However,
Loyal Adventurer 1: I aced my finals today.
Loyal Adventurer 2: OMG! THAT'S AWESOME!
Loyal Adventurer 2: CONGRATS!
Loyal Adventurer 1: Thanks!
Loyal Adventurer 2: I flunked out of school, so I never got to take a final. How was it?
Lovingly Mistaken Ranked Member: caps.
Loyal Adventurer 2: ...
...is not.
Although, and to be fair, almost anything that comes out of kisos' keyboard whether caps or not could potentially be considered SPAM.
Let us not rebuke the excited member for attempting to truly express their feelings. I may not be excited to be doing some thing. I may actually be EXCITED.
Love and huggles. You all ROCK!
