The yellow background however is stressing. If you like yellow to be your signature color, use it on a single element like a header strip or so.
Also, go get a custom domain for it. When your app gets popular and you do that later, many people have to update their links.
As for the custom domain name, I wanted to test it first before buying a domain. I used to buy the domain first and write the app afterwards. But most of the time, I was left with a domain name and no app. But yes, you're right, doing things properly requires a domain name. That'll give me the opportunity to change the name — since firetweets was just chosen randomly a long time ago.
Besides that, it really doesnt look like every other site. Almost all other sites are spoiled with eye sugar.
And as for simplicity, I'll quote St Exupery:
>A designer knows he has achieved perfection not when there is nothing left to add, but when there is nothing left to take away.
I certainly don't believe that this design is perfect, but it fades away to let the content shine.
Agreed. It's a lovely shade of yellow, but in front of maximized window on a 24" monitor, my eyes physically squinted a little when switching to it. :)
edit: changed to white. I'll provide the theme switcher in the next release :)
