I've heard this question quite a number of times and the answer is quite simple. Two years ago, I wanted to 'improve' Sinah Ntholi Nkoane and I had to come up with a name for the project where people can also share photographs.
My grandmother was turning 75 at the time, and well, I moved with that. The idea is fairly simple, I am hoping the least each photographer will do is post, 75 photographs, that is 1 photograph per day for 75 days, collectively.
Once they reach the 75 mark, they can then invite 3 more people (that they want to). Then the circle repeats, until-until. 75 might sound like a large number, but think about it's only 2 and half months and considering there is at the moment, about 10/11 photographers (i like prime numbers), in 75 days, that would ammount to 825 photographs, assuming everybody posts every other day. Now as soon as the current, rockstars, start inviting, the mathematics gets out of hand, I think the number of photographs will be in the same order like compound interest, well, something like that, I'll spend the night working out the formula, :-)
The premise is, if I had allowed anybody who registered to post photographs, then it would be another Flickr with a group rule. I do not want that, I don't like stealing people's ideas. Secondly, it was possible to run this project on Flickr (applying the group rules), but, flickr limits you to 200 photographs if you don't purchase the annual pro-account. 200 is too small for what I have in mind, I am hoping this will last way beyond 5 years.
But, in the future, I will build a Flickr interface, so those that cannot post photography, can share theirs, albeit from the outside.
Alas, I need to start planning for the 'Beta' version, with new improvements or, how do the say, 'new functionality'.
one.
