Sorry, your premise is way off. First, your 'another way..' jump is a logic failure that is completely off mark. Second, my post saying people don't understand twitter is not because they don't appreciate it, but because they have directly demonstrated their lack of understanding of twitter.
In a nutshell, because it's Friday night and I don't feel like spending that much time on something that should be self-evident to any objective reader:
You say that people are "dismissive" of Twitter, fail to "find[] value" in it, and "flush the whole thing." In other words, people don't appreciate it.
You also describe a bunch of things that Twitter can do, and contend that people "miss all that," because they still have an erroneous notion that Twitter is only (or primarily) used for describing when someone "'takes a dump.'" (As an aside, if such an announcement doesn't constitute an example of "tidbit sharing"

, I don't know what would...) In other words, people don't truly understand Twitter's full functionality.
These two concepts -- people not appreciating Twitter, and people not really understanding it -- are inextricably interwoven throughout your post. Connecting one to the other (and vice versa) probably isn't even implied so much as directly expressed; you explicitly state, for example, that when people "discover those uses" (i.e., when they better understand Twitter's full utility), the "tool starts to make more sense" (i.e., they begin to gain an appreciation for Twitter).
I'm not sure why you'd disavow one of the underlying points of your post, unless it's solely in an attempt to discredit my logic.
Actually - no, I'm not passionate towards twitter. I only use it for limited things. I personally prefer FB fan pages for a lot of simple following. But what I am is -- is informed of it's uses and values and know why it's so entrenched as a news tool. I can appreciate and understand things I'm not personally vested in.
For someone who's not passionate toward Twitter, you've produced the longest, most drawn-out defense of its uses and values I've ever read on a message board.
