it's certainly a lot simpler than anything you've proposed; oh wait, maybe not, that'd be nothing.
Yes, you cannot be simpler than changing a constant-- but as I pointed out, changing a constant is no measure of safety, correctness, or ethics. There are plenty of one character changes that would utterly destroy the system if adopted.
And contrary to your claim, I've proposed many things--- even going back some time. For example, adjusting the limit to respect the impact on UTXO so that the costs better match the actual costs; adjusting blocks based on the 33rd percentile of miner preferences (similar to Jeff's proposal of 25th percentile), and allowing miners to mine blocks over the limit quadratically with increased effective-difficulty-- so if the network is actually backlogged with fees miners can catch up without being completely unhinged.
And then there is all the separate fundamental scaling work which I originally proposed, like the whole notion of UTXOs as a separately tracked and commutable resource, fraud proofs, etc.
apparently the initial software is very buggy; not unexpected.
Huh? Dunno what you're talking about there! The network has been running flawlessly. While we're sure there are, no doubt, lots of issues-- as we optimized for adding interesting features instead of QA-- and you really really really shouldn't go create an altcoin out of it (because it will crash and burn and we will laugh)... it works quite well, and I'm not aware of any complaints to the contrary. Are you unable to exit FUD-everything-gmaxwell-touches mode for even a moment?
There really should be more interest in Confidential Values. That's a great technique.
Thanks. There are a couple of other angles that I think more people will be excited about once they 'click' for them.
Tying the subjects together-- for a given state of technology and amount of extra capacity (be it bandwidth, cpu, etc.) that capacity can be spent in various ways, by taking on increased load, by improving fungibility or privacy, by increasing decentralization. I happen to think we need all of these things. But a simplified understanding that only looks at one dimension isn't going to come up with a good engineering conclusion. And sure, more X sound great if you consider it in isolation, but perhaps not when you realize it means less Y and never gaining any Z. One of the reasons I think it's important to be cautious here is so that we can have CT (or a superior successor technology) in the Bitcoin network and not just in a sidechain.
