I wanted to share the following article via my twitter: http://community.jboss.org/wiki/InfinispanDistributedExecutionFramework
So I used ShareThis and clicked Twitter icon. It generated the following Tweet content for this:

====== start
Infinispan Distributed Execution Framework - JBoss Community http://t.co/Uhxwsif
====== end

The problem is that the link http://t.co/Uhxwsif does not take me to the desired page but to ShareThis site instead. Is this expected? Do I have to be registered with ShareThis first?
