Just discovered a new way to use Twitter*: automatically posting a link to my every new blog post.
All you need is an RSS feed (like this) and an account in Twitterfeed. Log in, and click on create a new feed. Choose your destination as Twitter, enter your Twitter login details, and then your RSS feed URL.
You can set how often Twitterfeed checks for new blog posts (least being once a day, at most 5 times every 30 minutes). You can deactivate the service anytime.
Twitterfeed can also post to identi.ca, custom laconica installations, HelloTxt and Ping.fm.
Follow me on Twitter!
*Or annoy your Twitter followers, depending on how you look at it.
