Usability 
Diggpad (wampad.com/digg/) is the work of Shawn Mccollum of Wampad. It takes a little different approach to Digg.com than the other mobile Diggs. Wampad is a mobile meta-search site so not surprisingly Diggpad lets you search Digg. 
Below the search box there are eight links that take you to the latest from Digg's seven topics or "All". Unlike the other mobile Diggs, Diggpad only displays the top nine diggs for the category or query you entered. Nine titles fills up my mobile's screen and exploring nine Dugg sites certainly keeps one busy for a while. Still, It bothers me that I can only see nine Diggs. I'd like to see a more link at the bottom of the screen to bring up the next Diggs. When you on click a headline in Diggpad you go first to a landing page with a fuller description and a link to the dugg site transcoded by Google. Using a landing page adds a click but it lets you scan more titles without scrolling - a good trade off for the small screen. Accesskeys also add usabilitity to Diggpad.
