That's great, looks really slick! I know you've posted what you'd consider for 2.0, if you are taking suggestions my ideal non-emacs org would be iOS compatible and sync with webDAV/Dropbox.
I like the design. I'm working on a similar service to bring org-mode to more people other than Emacs geeks (similar to how Slack brought IRC to a wider audience).
Current productivity tools fall quite short in comparison.
Org-mode can be used without being an emacs geek though. The wife of the friend of mine who first showed me emacs and org uses it as a self-management / note-keeping application, and whilst she might be at least slightly geeky, she's not really a tech person.
Once I found out how much you can really do with it, I went on a prosetylizing spree and got a couple of friends as well as my little brother into it. Whilst they're somewhat tech inclined, they're by no means emacs geeks, but they got into it after me showcasing and explaining at least some of the features.
Personally, i think that the only thing that's really essential in getting people into it is a tutorial level to it, similar to interactive tutorials for programming languages (I recall a marvelous ruby one from a year or two back, but I'm unable to find it). Org-mode already scales beautifully regarding complexity, and i think the main thing that turns people away from it is that the manual is a literal textbook and only silly people study it back to back. Or that they're using vim and don't want to switch to emacs, but that's not likely the group of people you're targeting.
Just this week I started learning org-mode by reading one of Charle Cave's postings on how uses org-mode to implement the Getting Things Done methodology http://members.optusnet.com.au/~charles57/GTD/gtd_workflow.h.... For me this has been a great tutorial.
To give you a kick start; things I would consider for Yipgo 2.0:
* Lots of people understandably don't trust an unknown company/person with their potentially secret TODO lists - add dropbox/drive support from the offset. Also means emacs/vim users can hack the files directly.
* "Normal" people like the agenda and wish they could interact with the items from it - defeats the point, but after yipgo was on lifehacker, I picked up a new type of non-technical user who now make up the majority of my users.
* Make sure it's mobile friendly (turns out the editor I chose doesn't work properly on Android, or at all on IOS).
* Possibly a Yipgo 3.0 thing, but people editing at the same time, ala docs, would be great (something I've wanted).
Actually, if you want to get in touch to see if we can combine forces drop me a mail, phil at apiaxle.com. I'd quite like to monetize the service if possible.
IMO if you don't trust an unknown person with your potentially secret TODO list, then you shouldn't trust Dropbox, Google, Amazon or Microsoft either.
My secrets are on an air-gaped fully encrypted PC. Apart keeping everything in my head this is the best I can come with, but it's still not secure enough for my liking, especially since the whole Truecrypt debacle the doubts are killing me.
I would have thought that the case too, but it really is my number one request from people. I guess Dropbox and co. put a lot of effort, money and people into security making them the better of the two options.
