I strongly disagree. They're chatty and irrelevant:
- How you pronounce a word isn't a shibboleth: you're not going to get fired for pronouncing SQL as "sequel" or "ess-cue-ehl".
- It doesn't help you do your job better.
- The correct pronunciation largely depends on who you're speaking with.
They're a textbook case of soft, bike-shedding questions. Unable to answer a question about a real problem? Who cares! Tell us your opinions on how to pronounce this word.
In the rare cases where there actually is singular correct pronunciation, they're either:
- off-topic because this isn't English.SE
- wholly uninteresting because any dictionary will tell you the correct pronunciation. Want to know how to pronounce ASCII? Look it up.
If you take a look at the answers to other questions in the pronunciation tag, you'll note the answer received on the hexidemical question is the exception, not the rule: people wildly upvote crap answers like "I always say {insert pronunciation here}." that have no justification or explanation. They bring down the rest of the site.
Aaronaught, who is always wont to crystalize the problems with a class of posts, gave a great answer when we were discussing if we should have a "general reference" close reason:
Unless we get a "too easy" close reason, I think we should close these as off topic. The word "expert" is right there in the site's tagline; if it's not relevant to an experienced, practicing programmer, then it's not in our scope. I'm sorry if it sounds callous, but we're here to help each other, not educate every single newbie on how to program.
Check this out:

I'm pretty sure that the purple area between "Advanced" and "Disciplined" is where we are supposed to be. We focus entirely on the subjective (objective questions go on Stack Overflow), so we have to be on the right side; and since we're nowhere near as disciplined as Skeptics, we have to make up for it by discussing subjects that are more advanced.
If we start allowing questions that are subjective and beginner-level, then we end up with bike shed questions, which almost invariably produce crap answers and drag down the rest of the site with them.

, that's how you're going to pronounce it, even thoughess-cue-ell
is probably more "correct". I can't imagine a more futile exercise than trying to convince all of your coworkers that they have been using the wrong pronunciation for years.
