I've already responded to this. Wired implies that Tweetie is a killer app if you use Twitter with multiple accounts. That's an edge case even among Twitter users, and Twitter is not an enormous web site. It's like saying the Facebook app is a killer app because it's gorgeous and provides near-full site functionality right now. It is, and it does, but say I'm writing an article about an app that I'm claiming "justifies" your entire app purchase. It doesn't help me look serious when I go on to say "Oh, also this one Twitter application is just as justifying. Seriously, accessing Twitter like this is as important as being able to store and read articles offline."

just as I expect that people who believe in the myth of the Wonderful Hacker News Comment Community will downmod all such comments into oblivion

It's not the sarcasm that isn't welcome. It's the sarcasm when dealing with subjects worthy of discussion. You know? Here we're talking about something that's provoking a good deal of debate, so your sarcasm is actively harmful to the discourse. If we were talking about some ridiculous subject, then sarcasm is totes coo'.

As for "discourse", well, I've been active here for a while and lurking for longer, and my first impression was that HN was a site that syndicated TechCrunch articles. Took me a while to realize there was anything other than an echo chamber here, and I'm still not entirely sure about that.

Shit like this isn't even snarking. It's just you being an asshole. Come on. We're all venerable old men here, we can afford some courtesy.

The iPhone is killer, but when Wired is making the argument of "Instapaper justifies your owning an iPhone", it hurts the argument a lot to add "just as much as this Twitter app will". Tweetie is nothing ultraspecial. Instapaper might be. It hurts to compare it to a web site client.
