Easiest way to do it is to assign a category for tweets (you can exclude the category from showing up on your  blog) and then pull the feed from your twitter category through ping.fm, hellotxt.org og hootsuite.com to publish the tweet on twitter. You then just need to write a new post, assign it to your twitter category,  set the publish date and off you go.

Of course that would quickly get pretty basic so I thought – what if you could track @replies to the individual tweets and pull them in as comments in your WordPress installation?  - and replying to those replies would then create new posts/tweets on your blog. All of a sudden your WordPress installation will have turned in to a Twitter-app…

So… any crazy input from you?
