I created a video to show some friends how to add a tweet this button to their blog posts (on wordpress). Tweet this adds a button to the bottom of your posts, making it easy for your readers to tweet what you say. It can be set to shorten the url’s, add facebook, digg, stumble upon, plurk etc buttons.
There are many, many twitter tools, some of which are wordpress plugins. Plugins add functionality to your website. I think they are very cool. Only add and activate plugins which you want to use on your website. Sometimes a plugin may have a conflict with another plugin. So I prefer adding one new plugin at a time, making sure my wordpress website still works, etc. Some plugins, too many plugins may slow down the load time of your site. Have the plugins you use serve a purpose.
Adding Tweet This Plugin to a WordPress Blog (and you can do the same thing to add other plugins–a fun thing to do).
