Spaced repetition

Here's a fantastically researched article on spaced repetition. It's so well-researched I'm going to try this myself, using Mnemosyne.

It would be interesting to find flashcard sets, like, everywhere and use them for domain frameworks or something. Unfortunately there are no prepared Mnemosyne sets for Hungarian.

It would be much *more* interesting to do some kind of gamification site.

Gamification of quant skills

It would be cool to explore gamification of quant programming skills in a tutorial website.

Business and revenue models

For some popular Internet destinations. This is good stuff!

Dark patterns: the Machine Zone

Ever spent three hours before bed zoning through pictures on Facebook or one more funny post on Reddit?  Sure you have. That's the Machine Zone, and it's kind of a human failure mode.

Forum/Twitter/email intermediary service

There are lots of people out there in public life (bloggers, game developers, etc.) who simply don't want to deal with obscenity-laden death threats on a daily basis. It wouldn't be that difficult to set up an intermediary service that would permit filtration of this stuff, perhaps coupled with law-enforcement reporting for anything credible.

It wouldn't necessarily even need to be that expensive.

This could kind of hook into a generalized social-media interface that could coordinate multiple services.

Zero to revenue in five weeks

Some kind of exploration support tool would be neat. Here's a quick little vignette about how this approach to online services can work.

Outbox

A service to pick up your mail and digitize/handle it for you, charging $4.95 a month in select markets. That's surprisingly low to me, since they actually go to your place with a key and get your mail (urban apartments) - not every day, though.  Still impressive.

That's easily clonable for any local market. Eventually the PO Box providers will surely also add that.
