Singing to the choir here, fella. I remarked just the other day on an MSNBC transcripter violating this rule.
I saw your comment and I was gonna post a similar experience and had no time. Just that same day, I posted a link to an embedded video. At the link, whoever posted the video transcribed the content. I was going to repost the transcription, but it was so filled with typos, dropped words, punctuation errors, and capitalization errors, it made more sense to just suggest people watch the video.
I mean, people are going to mistype things sometimes. But at least try, for Pete's sake.
On the other hand, what the hell difference does the tossing of just another insignificant rule in today's world make, right?
It matters. Don't ever let them convince you it doesn't. It just feels that way some days.
ETA: BTW, this was just an email joke my dad sent me.
