WordTwit is the first one, and this is a good one for you Twitter users out there with a WordPress website. Basically, it makes twitter updates for every blog post you make. That way tweets are sent out automatically to alert your followers on Twitter about new blog posts. This post will be my first trial, but I think this is much better than doing it manually.
This is an old photo set of mine, but it helps demonstrate the function of this plugin. Really useful instead of pointing people to Flickr to see the rest of your pictures for something that you have a bunch of pics about. And let’s be honest, people love looking at pictures just like many folks read the newspaper for the funny pages.
