Twitter via the normal Service or Twittermail
Schmie_twitter is really awesome! When you update or publish a new post on your WordPress Blog,
it will notifiy your followers on Ping.fm Twitter and / or Identica!!!.
You can define default messages that are pushed to your Message services or create custom Messages for every Post. If you're hoster blocks Twitter (like my Hoster), you can use Twittermail. You only need an emailadress on your webspace. The plugin supports several Url-shortening-services (is.gd,bit.ly,i2h and tinyurl). If your favortive service is missing, write me an email (email@example.com). It is possible now to use Ping.fm. All you need is of course an account there, The User Api Key and an Api Key.
