I'm not going to try and evangelize Twitter. I figure you're probably already addicted to it, dead set against it, or blissfully ignorant of it. I don't think it's the be all and end all, but I'm rather enjoying it. If you're so inclined, you can follow me there as limeduck.
But I am here to share some geek notes on consolidating your blogging and microblogging, if that's the way you roll. Inspired by Sockington the cat who has over 200 followers on twitter, I set out to find a way to automate my twittering. I found TweetLater, which allows you to schedule some time-release tweets. More interesting was twitterfeed, which allows you push RSS feeds to your twitter stream.
Twitterfeed uses openID for authentication, a welcome change from having to create yet another user account. It has a number of useful options such as the ability to prefix RSS tweets with some text to identify them as robotweets. In an interesting twist on the usual "beg button," the creator of Twitterfeed asks that you consider a donation to Burma Cyclone relief. I second that. You can go to Twitterfeed's suggested charity, to my fundraising page, or to your favorite international relief charity.
So I've now set both this blog and my work blog to push their posts to my twitter stream. The complementary step, much more straightforward, was to add a WordPress widget of the RSS feed of my twitter stream. It's a the bottom of the right sidebar now.
Next stop, figuring how to wire this all into and out of Facebook. I can see the dangerous potential for infinite loops or disturbing depths of self-absorption. Proceed with care.
