The biggest problem face being on Twitter is that they do not write quality Tweets. The way to make people click on your links or profile link is to write tweets that make people curious enought to visit your sites. I have found that TweetArchitect is quite a good nice little tweet editor http://download.cnet.com/Tweet-Architect/3000-12941_4-10974504.html?tag=mncol#rateit
Your website link is not working. Make sure that you have entered the correct one. On the other hand, I am not able to understand, what it does properly.
The links works for me without problems, just go to www.download.com and search for "Tweet Architect" http://www.youtube.com/watch?v=mkdYN5zUQ8E
