I have been pleasantly surprised by the uptake we have gotten for the Windows Live Writer SDK. We have had thousands of downloads of the SDK and in just over a week there are already a dozen plugins available, covering everything from Flickr and SmugMug photos to ink-blogging.

A few resources for people interested in either building or trying out plugins:

• Keyvan Nayyeri has a great article on creating plugins 
• JefTek is keeping a running tally of available plugins.
• A number of the projects underway are being hosted on CodePlex.

In late September we will be rolling out a new section on Windows Live Gallery dedicated to Writer plugins (more info on this will be available soon).
