I recently created a new “Roundup” blog category, in which I list (with links) articles, blog posts, and vendors sites that I find. This has given me an idea for a new blog feature, offered here for comment. 

As a personal knowledge management tool, blogs are pretty good, but have limitations. Searching and reporting are limited, at least compared with databases.

When I blog, it would be useful to cause selected text to appear not just in the blog entry, but also as a database record. Some might argue that I should just use a tagging system such as del.ico.us. But I’d like something as an author that is more integrated and database-like.

Does this feature exist? Would it be useful to bloggers? To law firm librarians or knowledge managers?
