The "FAQ" page has been changed by gdusbabek.
The comment on this change is: explained why autoboostrap=false is a bad idea 
when introducing empty nodes to a cluster..
http://wiki.apache.org/cassandra/FAQ?action=diff&rev1=92&rev2=93

--------------------------------------------------

  
  In Cassandra 0.5 and above, there is an "AutoBootStrap" option in the config 
file. When enabled, using the "-b" options is unnecessary, because new nodes 
will automatically bootstrap themselves when they start up for the first time. 
It is recommended that you leave "InitialToken" blank for these versions, 
because the improved bootstrap process will pick a balanced Token for each node.
  
+ Under no circumstances should you introduce a new empty node to your cluster 
and have autoboostrap disabled.  In version 0.7 under write load it will cause 
writes to be sent to the new node before the schema arrives from another member 
of the cluster.  This would also indicate to clients that the new node is 
responsible for servicing reads for data that it definitely doesn't have.
+ 
  In Cassandra 0.4 and below, it is recommended that you manually specify a 
value for "InitialToken" in the config file of a new node.
