A video is worth a thousand screen shots
Every time a new KimDaBa user shows up, I hear the same sentence over and over again: This is exactly the software I need, I just wish I had found it a long time ago.
Now if KimDaBa is that good, why isn't everybody in the whole world using it? One reason might be its name, and I am considering renaming it to something boring but more obvious.
Another reason might be that it is different to many other photo managing applications in some ways. This is not a bug, but simply because it approaches the problem differently, which is it's strength.
To remedy the problem with the initial learning curve, I've recorded a number of introduction flash videos, which includes voice to explain what the user sees on the screen.
Have a look at http://ktown.kde.org/kimdaba/videos/, who know, you might be my next happy user.
