As a competitor, this is exciting. Updn is effectively what valME.io [1] does (although valME has many more bells and whistles, doesn't require someone technical to install and run it, uses bitcoin and PayPal, etc.). It is especially encouraging to see this open sourced. One of the goals of valME is to find ways where content consumers can bypass the behemoth publishing and media industries and financially support ou…
Yet this site looks only marginally more alive than, say Digg. You've provided a content /aggregation/ site that you now have to pay for in order to actually contribute or effect in any way. It isn't really about the amount or the method in which you pay, it's the fact that you HAVE TO. Reddit is constantly mocking itself and the karma system because people are scamming other to get worthless internet points. Now you want to try and tie a dollar value to that and think that you're innovating?
Granted I think some of your ideas are actually interesting. Creating a micropayment system for content creators (Note: not content gatherer) to allow more independents to thrive is a wonderful goal. You however seem to be creating exactly the opposite, where money can be quite literally thrown at a post in order to force it into visibility. More so Updn (not sure about valME) has a cost associated with down-voting. Enter Company A which drops, say, 20$ to put in hundreds or thousands of upvotes for a press-release. Users would effectively have to pay to get an advertisement off their front page in order to find anything worth a damn.
My final point will relate to your philosophy and as such is totally subjective. I honestly don't understand where your remarks about "something for nothing" actually relate in this post, but I find them borderline absurd. You brush aside those who create for the sake of creation, like I would imagine the tens of thousands of coders and designers who frequent this site do on a daily basis.
You seem to strive to bring together as many soundbyte worthy ideas as possible to entice people into using a product that, it appears, no one wants to. The the space of a few paragraphs you mention: overthrowing advertising, supporting independents, copyright legislation, encouraging youth, Ann Rand-esque philosophy, distribution of wealth away from corporate entities, and copyright lobbying. All in all this sums up to something slightly less than a bad joke.
