The Bee Blog has a good idea about substituting a blogroll with the latest buzz (posts) from a blogroll.
You could do this 2 ways:
Problem is my Bloglines OPML doesn’t have an RSS feed, I’d have to use a tool like FeedDigest to splice all the feeds in my OPML into a re-mix RSS feed…or export my OPML into a Blogdigger Group, which in turn has an RSS feed (then whack the java code into the sidebar).
…see more here.
The other way has a step before seeing actual post titles
…splice all your blogroll or OPML (I guess your blogroll may be just a portion of your OPML) into a feed at TagCloud, then re-syndicate the code of your-computer generated hot keywords-from your blogroll/OPML into your sidebar.
In this way, from your sidebar, you can click on hot keywords from your blogroll/OPML, this takes you to the TagCloud website to view these posts.
It’s almost like having your RSS reader (OPML) content (organized by keyword) on the sidebar of your blog
