I am working on https://datkey.com, and the UI design and UX aren't working out.
How do I build a good quick set of images for a simple splash page or convey quickly to the users the concept of organizing their cloud?
I would add to Jojo' answer that :
In order to explain the concept I think you're on the right track with "Browse, collect, share". Those steps in the workflow logically follow each other, and are not too difficult to understand. Your current design is inconsistent though: the total control box uses a different order (organize, share, browse) that doesn't make sense.
1) Browse (with supporting icons for the social media sources - I don't need to know that I can share both my tweets and followed tweets, just twitter/linkedin/facebook/youtube/google is enough at this point)
2) Organize (what does that mean in your case? is it folders? sorting? labels? annotations? use either a clear image that illustrates the process or a screenshot of sorted items)
3) Share (with images about sharing)
Play a little with those 3 items (boxes, arrows, numbered steps, ...) and I'm sure you can come up with something.
I support JoJo's opinion. What I have to add is:
There is plenty of space for main menu at the top between logo and login part;
I miss the registration link so I could join smoothly when coming for first time at the site;
I think there is too much graphical information (icons + text). I personally would prefer it to be one solid image explaining the whole idea or see a link to a detailed manual of use, etc.
I hope that is helpful to you.
