I love discovering new sites and services on the internet, and this one certainly caught my eye. It's a new site for online invoicing and client management called Ballpark (great name!). They have a nice demo video that walks you through a typical use case (though I don't think Nike needs a new logo). The design comes across as clean, organized, and has a nice hierarchy of information layout - colors to indicate status, big clickable buttons, and large type. There are clues of Basecamp in regards to the layout (leaderboard across the top, main dashboard w/right column), and the homepage reminds me of Campaign Monitor. Both these sites sell web services, and excel at communicating, so it's completely natural to fit this style. I look forward to signing up and digging deeper into the site.
