The target is not to buy or sell side projects, it's to show your work to the world. A sort of "Show HN" but searchable and only dedicated to side projects. So it's a kind of a directory ;-) There should also be an option to let the readers know if someone searching for help. Use-case: Someone is a good developer and has programmed an nice app. Because he/she is not a designer the app has a poorly UX. Then he can tells inside the post on Kilaluu that he is searching a designer - someone who is passionated and want to join this side project.

I like the idea of focusing on one use-case, one niche.

Thx for your help :-)
