Clicking the up and down arrow on HN seems to work OK. Similar voting or comment moderation systems on reddit or other places are sometimes reasonably fast. I would not mind selecting a pull-down or radio button and hitting submit at the bottom of the page, however. In fact I'd prefer it. And there are more examples of such systems poorly implemented, often to the point that they kill the usefulness of the site. Slashdot's firehose with it's + / - buttons is like that, and slashdot's main page has become like that, but I am logged in have as many "new features" turned off in my preferences as possible. When I type text into a box on Facebook, I can outrun the letters appearing by several sentences. There are numerous sites that use various kinds of javascript rich text or html editors that are also pretty unuseable. I like gmail, but not it's javascript features. I use the basic html setting, because if I live it up with the normal setting, my browser will become unuseable after a few hours. It was particularly bad in some of the previous versions of firefox, which apparently had some memory fragmentation issue regarding parsing javascript, but as javascript brings no benefits and makes the page take slightly longer to upgrade, I have never switched back even now that I have the latest upgrades to the browser. I like google maps as an application, and I use it pretty extensively, at least once a week. I don't find it's panning arrows and so on particularly appealing, and I habitually restart the browser after using it, to clean out any javacrap memory issues remaining. And it is not simply the idea of the type of interface google maps has that I object to: for example, I love Google Earth, and I like to change the angle of view and rotate around various landmarks and so on. This is on the same computer where I turn off java script for gmail. So it's not just that I have some Amish insteance on older interfaces. It is that javascript in the browser sucks. Now, that doesn't mean you won't make a billion dollars making a web site that depends on javascript, of course. But all other things being equal, I think you should focus on interfaces that are very simple and very fast if you want to get adoption. It's probably more important to hand-code your html and run it through packing scripts that remove all whitespace and etc, to really scrape every last byte out of what is sent to the user, than it is to have an up/down arrow that automatically submits to the server.
