After yql-yui-and-jquery I tried to make a widget using the same killer combo.

Hacker news widget
Displays top ten news from the front page of hacker news

Ingredients:
0. YQL rest url for the data.
1. jQuery for getjson().
2. YUI css's for looks.

How it looks?
Check the demo HERE

What next?
0. Get the code from here
1. Improvise it :) Like an android app?
2. Share better methods.
