You've misunderstood what "TL;DR" means. It means the writer thinks their *own* post is too long, so they're providing a short summary for those who don't want to read the whole thing. It's like "SKI" (summary for the Klingon impaired), except for the time-impaired instead.
The thing is that long posts might be off-putting to mailing list members who might have an opinion about something, but don't want to engage in a grammatical dissection or a debate. But long posts tend to generate long posts, because a person replying to one might feel like they might be accused of avoiding the issue if they don't address every point. A "TL;DR" allows people to reply to a long post with a short one, by ignoring everything not in the "TL;DR". It's not an insult (at least, that wasn't its original purpose, though perhaps some people use it as one).
But anyway: does *anyone else* have an opinion of what {reH latlh qabDaq qul tuj law' Hoch tuj puS} means, and what the comparative grammar is doing in that sentence? (Short answers only.)
