Previously: Is it time for a Home Improvement blog?
The chat session yesterday discussed some projects people were working on and recent experiences, and then started talking about how we could store and share these experiences to build traffic. While many of us have our own blogs, flickr pages, and other sites, it's difficult to aggregate these in any meaningful way with the current structure of the site, and we may as well give people a place to post their own experiences if they don't have a blog of their own.
Per the "So how does my site get a community blog?" section at Blog Overflow, the second step is determining what the scope, organization, and purpose of the blog is. I'll take a shot at it in the answers below.
