I also have IBS and was diagnosed years ago, but I never heard of different classifications that you mentioned, IBS-C or IBS-D. Mostly, I classify the severity as "day-to-day", workdays usually being the worst. I haven't tried consuming live cultures other than yogurt, and even then I have mixed results. Have you gotten far in your research on the types of bacteria, and do you have any resources you could share?
Edit: just read about differences between IBS-C and D and it definitely sounds like there has been some headway in the last 15 years since I was diagnosed (back then it was mostly a prognosis of "here's a colonoscopy, sorry not much else we can do"). I should definitely get re-evaluated. Thanks for mentioning this.
He's not better than that. You have to remember, he caters to an Apple audience. Because of this, when he is critical of Apple, his tone is soft and non-threatening so as to not offend his audience. When he is critical of his competitors, he often takes a hard, holier-than-thou tone in his posts to enforce his audience's affinity for Apple. In other words, his blog is highly polarizing by design.
This isn't a bad thing, every product needs their evangelists, but we must not confuse evangelism with journalism (not saying you did that, but I mean in general).
I'm there too. I often measure myself against the fact that Einstein invented the theory of relativity in his early 20s. Meanwhile, I'm 30 now with a Masters degree in CS that I feel is worthless, writing what amounts to string concatenating programs all day at work.
The only thing that keeps me sane, really, is a combination of doing iphone development after hours and playing with arduino. It also helps that I have an amazing wife who is unrelenting in pointing out my accomplishments, however worthless I may think they are.
