A little over a week ago, the Popfly team announced a new version of Popfly which brought several changes to the tool. Most notably, was the edition of a data source editor which lets you bring your own data into the mashup designer. Your data, which needs to be in .CSV format, is shown in yellow blocks in the program. The update also offers an improved search interface, the ability to upload images and other files to your block, comments on profile pages, better ways to invite friends, and a help wiki. There are also new blocks available now, like the MovingSlideShow block for smooth panning and zooming transitions and the RSSList which would be great for use in blog's sidebar.
