by themes/designs you mean skins? That's the plan. I will provide as many different skins as possible and I'm also looking to integrate it completely with twitter/github/flickr/youtube/etc. Besides that I may also provide a visiting card psd matching the look & feel of theme as a freebie.

Right now, I was itching to launch it so I did it with very basic version.

Please provide suggestions on how else to improve it?
