So I had a drunken dream about online microcurrencies last night. Also about cats and water-slides but that’s another story. Idea was of a karma donation system based on one-off assignments from person to person of specified chunks of their lifetime; ‘giving the time of day’. you’re allowed to give any time of day taken from those days you’ve been alive so far. they’re not directly redistributable, nor necessarily related to what happened during the specified time. there’s no central banker, beyond the notion of ‘the public record’. The system naturally favours the old/experienced, but if someone gets drunk and gives all their time/karma to a porn site, at least in the morning they’ll have another 24h ‘in the bank’. Or they could retract/deny the gift, although doing so a lot would also be visible in the public record and doing so excessively would make one look a bit sketchy, one’s time gifts seem less valuable etc. Anchoring to a real world ‘good’ (time) is supposed to provide some control against runaway inflation, as is non-redistributability, but also the time thing is nice for visualizations and explanation. I’m not really sure if it makes sense but thought i’d write it down before i forget the idea…
One idea would be for the time gifts to be redeemable, but that i think pushes the metaphor too far into being a real currency for a fictional world where hourly rates are flattened. Some Lets schemes probably work that way I guess…
So I’ve been meaning to write this up, but in the absense of having done so, here’s the idea as it first struck me. I had been thinking a bit about online reputation services, and the kinds of information they might aggregate. Garlik’s QDOS and FOAF experiments being a good example of this kind of evidence aggregation. As OpenID, FOAF, microformats etc. take hold, I really think we’ll see a massive parting of waves, red sea style, with the “public record” on one side, and “private stuff” on the other.
And in the public record, we’ll be attaching information about the things we make and do to well-known identifiers for people (and their semi-detached aliases). Various websites have rating and karma mechanisms, but it is far from clear how they’ll look when shared in the public Web. Nor whether something robust and not-too-gameable will come out of it. There are certainly various modelling idioms (eg. advogato do their internal calculations, and then put everyone in one of several broad-brush groups; here’s my advogato FOAF). See also my previous notes on representing expertise.
Now in some IRC channels, there are bots where you can dish out credit by typing things like:
edd++ # xtechy
…and have a bot add up the credits, as well as the comments. In small IRC communities these aren’t gamed except for fun. So I’ve been thinking: how can these kinds of habits ever work in the wider Web, where people are spread across Web sites (but nevetherless identifiable with OpenID and FOAF). How could it not turn hideous? What limited resource do we each have a supply of? No, not kidneys. And in a hungover stupor I came to think that “the time of day” could be such a resource. It’s really just a metaphor, and I’m not sure at all that the quantifiable nature is a benefit. But I also quite like that we each have a neverending supply of the stuff, and that even a fleeting moment can count.
Update: here’s a post from Simon Lucy which has a very similar direction (it was Simon I was drinking with the night before writing this). Excerpt:
And what do you do with your positive balance? Need you do anything? I imagine those that care will publish their balance or compare it with others in similar way to company cars or hi fi tvs. There will always be envy and jealousy.
But no one can steal your balance, misuse it.
So who wants to host the Ego Bank.
The main difference compared to my suggested scheme, is just the ‘the Web’ and the public record it carries, are the “ego bank”, creating a playground for aggregators of karma, credibility and reputation information. “The time of day” would just be one such category of information…
