I have just tested a new plugin to my wordpress. Its the Twitter Tool plugin.
This allows you to crosspost from twitter and to twitter from you blog.
I have been on twitter quite some time and Im not shure how good it is and im not a god poster there. But this plugin helps by posting to twitter when I do a post on my blog.
It can do more – like posting to twitter, and also make blogpost from twitter but thats all configurable.
It seems to work well and im happy with it for now.
