Here's what I did:
- Create a new category to hold your new tweets. I created the Tweets category.
- Download, install and activate the Lifestream Wordpress Plugin. I pulled straight from the Subversion repository with the command (from the wp-content/plugins directory):
svn co http://svn.wp-plugins.org/lifestream/trunk lifestream
- Add a new "Twitter" feed to the Lifestream plugin. This will get you the most recent 20 tweets, which was not what I wanted. An earlier version of the plugin could download all archived tweets, so I downgraded to version 0.99.4 with the command (from the lifestream directory):
svn sw http://svn.wp-plugins.org/lifestream/tags/0.99.4
- Re-add the Twitter feed to Lifestream, which should give you all (or, at least most) of your archived tweets.
- Unfortunately, Lifestream does not set up Weekly digest posts for all the existing events/tweets that it loaded. So, I had to hack on lifestream.php to do that. If there's interest in the comments, I will post my diffs here. Let me know!
- I ended up with 42 weekly digest posts being created. Unfortunately, they all showed up on my blog home page, as well as in the RSS feed. Not what I wanted.
- Download, install and activate the Ultimate Category Excluder Wordpress plugin.
- Configure the Category Exclusion plugin to exclude the Tweets category from the Main Page and from the Feeds.
And, that's all there is to it.
Your Main Page and Feeds stay clean, but your Tweets (and any other feed/stream that you want to include) will get archived with your blog.
