I cringe at the thought of anything being decided by the masses, with their existing track record of music, movies, food, art, social mores, etc. I just think we need to realize that at some point the internet will outgrow the terrarium we've created for it, and at that point it won't be ours anymore. And in the grand scheme of things, that's probably a good thing.
But if your entire belief system is predicated around the idea that you'll be able to keep it inside that terrarium forever, I'm going to be really hesitant to put much weight in your thoughts on technology.
Though I must confess my ignorance here as I have no clue whatsoever as to who this Winer person is, or who's Scoble for that matter, so I'm not quite sure who it is that I'm defending, but I guess I'm defending the principle.
The latter position will almost certainly lead you down a path of ruin as you try to make your living with technology.
If you worked for a book publisher who couldn't even conceive that people might like ebooks, couldn't fathom why anyone would ever want to read a book on a digital screen, for any reason, you'd quit (I hope).
Not someone who thinks paper books are superior because of the way they feel, or that they don't have DRM, or that you can share them, lend them, resell them, collect them. Those are valid reasons to prefer paper books.
But if you work in the book industry, and honestly can't understand why anybody would ever want an ebook, you're not someone whose opinion about the nature of the book industry I value.
As to who these people are, Dave Winer is a technologist who played a very important roll in making RSS a thing (and he wants to make sure you remember it...for all of eternity), and Robert Scoble is a technoloblogger (he writes about a lot of services/apps from a user perspective) who never met a social networking site/iPhone app/ that let him promote that he didn't like.
I see :) And about the "can't even conceive" bit, well, I think he's just saying that. That's what idealists do sometimes.
Variety and alternatives are good. Opinionated software is good! Mono-culture, design by committee and one single way of doing things (no matter how good or efficient) are all bad.
For example, look at what happened to the US shuttle program, the public manned space program is now limbo because of dependence on a single way of doing things. Thank goodness for the private space enterprises bubbling along and competing on the periphery where there's a glimmer of hope.
Let structures emerge from the outer edges of the internet that are in constant flux. As long as we all agree on the basic protocols in the core of Internet, we'll be fine.
On the other side of this wider debate, my friends think I'm crazy for switching from a very nice Mac GUI, MS Office, QWERTY keyboard et al to Ubuntu et al and work my way up the command line, emacs and relearn Colemak keyboard typing.
I'm starting to enjoy the pay-off of my crazy efforts. My 'sensible' friends don't know what they are missing.
