This morning we deployed the latest version of Popfly to our servers. Here are three cool new features (among many) that you'll find with this release:  

• Tweaking. Easier than ripping someone else's project, tweaking enables you to change basic properties of that project and save it. For example, if see a great mashup that uses photos of cats, but you want to see dogs, you can now do it without needing to rip the entire project. 
• Integration with Dapper. Dapper is a tool that transforms web sites into other content types (e.g. RSS feeds or straight XML), so you can now take web sites that may not have associated blocks, create a Dapper "Dapp," then use the Dapp within Popfly. See the Dapper tutorial here.
• Embed in Facebook. Before, Popfly would publish a link to your profile page. Now you can embed an entire application. 

In addition, you'll see some other nice changes:

• A new, cleaner (and faster-loading) user interface
• Blocks organized by category
• Searching for projects, top projects, and top contributors
• The ability to email links to your friends
• Block properties so, for example, you can change things such as the frame color
• Digg and Reddit buttons

So c'mon back and give Popfly a try!
