The BackType Tweetcount plugin shows the number of tweets your posts get and allows users to retweet.
To use manual positioning,
echo backtype_tweetcount(); where you would like the plugin to appear in your WordPress theme.
Currently, we will track tweets for your posts for up to approximately three months (much longer than other plugins)
Add a custom field to your post named
bttc_short_url and enter the short URL you would like to use.
