If all of the developers made 1000 movie getting applications, then they would likely overlap data, targeting the same files all the time would enter into cache the most watched or loaded movies. So when this happens the applications will no longer gain Safecoin from those get requests to the same applications. So then 1000 applications will eventually have near zero returns in terms of Safecoins, and quickly reach that zero point everytime someone gets some new unique movie for the first serveral times.
So then the developers will now have no choice but to look for new applications to new forms of data on the network. The getting of data firmly relies on the putting of data: someone had to spend safecoin to get the data there first.
This leads to developers or people need to form a demand for new application for which they can use their safecoin to PUT different kinds of data.
So, all developers will stuff their applications with GET requests. Definitely.
based on maidsafe.net/safecoin chart I think this is a close guess to how much 400k GET requests to a forum could calculate to in safecoins per month from a forum application.
It seems more realistic with a figure like this. And makes a good perspective, remember that a forum wouldnt have all of the range of features of every application available, although it could., and just like any other application that hits a mark on utility.
