Marketo.com (The comapny I work for as UX Architect) is launching their flagship product and public site this week. Uses a bunch of jQuery, Tabs Plugin, Validation Plugin and Scrolling Promo Effect. Design was by (upon request). HTML Production was done by NetKitchen and myself. Overall, I think it’s a solid looking site.
One thing I have started doing is using more PNG files with transparency. You have to be careful in terms of filesize, but the transparency effect is quite nice.
I feel good about it. Specifically the black background which I think makes the whole page pop!
