Some people or bloggers who have their followers on Facebook as friends. They might not want to send all tweets to their Facebook account as it may spoil fun as well as seriousness of updates. Here is a solution for the situation.
You may want that some Facebook status stay longer but using official twitter account may update status too frequently as you tweet too frequently. Instead of using official twitter application you can use application named Selective Tweets. This application works in same manners as official application but allows you to choose what to send on Facebook and not.
To use this application first add and allow the application : Visit the application
Now to send any tweet to Facebook account just add a #fb hashtag in it.
