Thanks for the feedback. The background was originally white, and easier on the eyes, but it wasn't distinctive enough. The site looked like almost every other site. The yellow paint coat gives it charisma, but I might have over done it a little bit.

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.
