Strictly Tweetbot is a plugin that automatically posts status updates to multple Twitter accounts whenever new articles are added to the site.
This plugin is great if you want to do any of the following
-Tweet to multiple Twitter accounts when a post is added OR post to the same account with different formatted messages.
-Only tweet if the content of the post contains certain words, or don't post if the words contains certain words OR always post the tweet.
-Include a list of "noise/bad" words to ensure a tweet isn't sent if a post contains those words.
-Add tracking codes (Google) or other querystring values to the link to the post before it is shortened.
-Shorten your URLS with bit.ly before Tweeting.
-Get detailed messages back from Twitter including error messasges if the Tweet is a duplicate or their is an API error.
-Use the Tweet Shrink API to shrink your texts
-Use my Text Shrink API to shrink your texts with "text" speak e.g l8 = later, 2 = to.
-Use Categories, Post Tags or Default Words as #hashtags for your tweets.
-Automatic linkup with Strictly AutoTags so that the Tweets won't be sent until AutoTags has finished tagging your new article. Then these new tags can be used as #HashTags in your Tweet.
-Prevent Twitter Rushes by making an HTTP request to the newly posted article so that the post is cached before 50+ BOTS all hit the page from Twitter.
