"Hey, 10-4, good buddy!"
For those of you young punks who've seen this term on a t-shirt but don't know where it comes from (because you don't remember any part of the '70s, damn you), 10-4 was the ten-code for "Message received," "Acknowledged," or simply just "OK."
It's CB radio talk, which is how people talked to strangers before IM.
OK, fine: ten-codes are on the way out. But, there doesn't seem to be a lot else going on October 4th (besides World Animal Day?), so here's what I propose:
Let's make 10-4, October 4: Leave Someone Else a Comment Day.
* Do you read someone's blog religiously, but never say anything?
* Are you a leech on a social link sharing site, one of the silent majority (80% or whatever it is) who coasts and consumes what the super-sharers put out?
* Have you seen an image on a photo-sharing site you like?
* Do you lurk on a message board somewhere?
On 10-4, tell someone "Message received": Leave a comment somewhere where you haven't commented before.
Hey, we all know that the oft-quoted and universally-ignored maxim of user-generated content, "I do this for myself, not other people," is crap, so on 10-4, validate someone else's online existence: Leave them a comment, and say hi.
10-4: Over and out.
