I found my (Waterloo) apartment sublet listing more successful in attracting customers on Craigslist than Kijiji. Maybe different items are more successful on one space than the other.
I agree this will be the problem with service-like spaced repetition software like Memrise. They will start off with beginner examples and then totally drop off once you transition into intermediate.
My opinion is that SRS must be ingrained with your own interests. Additionally, the base decks on Memrise don't use further flash card techniques other than Q/A or word/definition. Cloze deletion cards come to mind when memorizing things much easier.
This is one of the problems. The framework is good, but content usually isn't. Content in SRS is really hard because language learning should collide with interests in order to feed the fuel.
More dedicated SRS users will just move to something more portable to create their content more easily/personally and beginners eventually drop off.
More context: As I'm jogging to work, there were students holding up boards with those posters right in front of the RIM buildings. I feel embarrassed as a fellow Waterloo student.
I can say that the letter has truth in it. According to previous employees of RIM, both co-op and full-times, it's more businessman than techies. RIM really imposes ownership over their employees' ideas as well. I walk by the RIM buildings everyday on the way to school/work. Sometimes I take a look at the faces of people walking to their own RIM jobs. I can really see the lack of passion for their work.

Anki's biggest goal seems to aim for cross-platform in use (even stretched to the NDS at one point).
