I've been dreaming of creating a platform that used crowd sourcing to map concept & procedural masteries to higher level masteries and to occupations.
Basically, a giant graph database mapping concepts, procedures, systems (versioned), and occupations. I think such a database could be used to improve learning management systems for school faculty and autodidacts alike. It could also serve as the basis for a performance/competency evaluation system that could replace resumes eventually.

#22Reputational Review Network - A review network where users can rate local restaurants, services, goods and other reviewers' credibility. Ratings are personalized based on your own reviews and who you find credible - this gives a user an incentive to keep their reviews honest.
One complaint I've heard is people looking for restaurants and finding 4-5 star rated McDonalds. Seems ripe for PCA or something. There are a ton of examples of this sort of analysis too, especially since Netflix made their datasets available. Here's the first paper I found: http://www.lkozma.net/mlsp09binary.pdf

So dwarf fortress with human village setting?
Perhaps Banished is more in line with what he's describing. http://store.steampowered.com/app/242920/
Thanks, that's very interesting to me but not quite what I had in mind. I'm thinking modern era, where the sims have links to an outside world - so some sims would commute out of the village for work each day, some would go to the nearby city for nightlife at weekends.

#24For me, it was a brain for my brain. I slung a lot of code to get what I wanted, but at the end of the day the encryption options are just not robust enough - or do not fit with other toolings needed.
Yes, I get this. I've been trying to code a virtual factory so that I can replace my actual factory and the overhead that comes with an actual factory. Just can't quite get there.

I think absolute ratings for restaurants in general tend to be garbage, since a rating is skewed to the average expectations of the guests.
The 5-star McDonalds may be a really good McDonalds that's very clean and consistent, but the $50/meal ocean-side bar only has 3-stars because the steak is sometimes rare instead of medium-rare. People are rating relative to their expectations of the restaurant, so someone who doesn't share those same expectations will be confused that a dollar cheese burger is 5 stars but a prime rib steak is 3 stars.

#26Bubble burster bot. Identify cliques with few "outside" connections, that talk about politics on a social network. Start engaging both groups with content "acceptable" to both of them. Continue until direct connections are formed and move on. "Content" can be trivial - like finding a link posted by one person and responding "similar to this, right? "
Potential risk: choosing bad content could cause more conflicts than new connections.
Why not done: just came up with it, also unlikely to be profitable unless you get a research grant for it.
Trigger: this idea is similar, right? https://twitter.com/Aelkus/status/796845589254275072

#27A Reddit alternative where the ranking for posts was personalized to each user. The ranking would be based the similarity between the voting history of the people who've voted compared to your own voting history. Think Netflix recommendation algorithm for Reddit.

#28A mood indicator for every person within a nation. Takes into account technical know how and intent to thwart. Think of everyone from people who dont even use phones to a SF techie. The goal is to share in parseable data what is important to you on a daily basis (or as often as you like) so that sentiment is not a surprise to fellow countrymen or governments, advertisers, entertainers etc.

#29A voting system for websites based on "liquid democracy"[0], where a pagerank like algorithm is used to let a person assign votes to others. The catch is this system would deliver personalized scores so each person sees a personalized ranking based on the votes they cast rather than an average of everyone's votes.
The idea is that people get a "bubble" but that when people vote, hopefully they take into account both quality and how similar the post is to their own. So people get a better version of their own views, which hopefully also allows them to see similar but non-identical views.
You can see that sites like reddit which tend to have high quality posts, but many subreddis have very strong biases as well. Letting people live in their own bubble means that people can write the best quality posts they can without worrying if their bias matches the subreddit they are writing in.

#30I have wanted to build a chat bot that acts as a counselor. I am quite sure it could be created with enough training data or at least be used for training. But it is difficult to convice anyone else that it's a good idea.
Here is an outline of the technical requirements and how they could be achieved.
