title: Xmarks, what languages are required to make this work?
body: <p>can anyone help explain the programming languages required to make Xmarks <a href="http://www.xmarks.com/" rel="nofollow">http://www.xmarks.com/</a> work?  i know they have servers that store your account information,  do you think this is handled by php/mySql or does this type of operation need something more robust like Hbase Hadoop?  also what language is required to communicate with all the different browsers?</p>
