Some review of installed packages is usefull from time to time,
ideally just after install, but before upgrade is also a good
opportunity. In synaptic, you can easily review the packages which are
"manually installed" and try to uninstall the ones you don't want; you
will be warned if this removal breaks something usefull.
'apt-get autoremove --purge' will get rid of all packages which
were once installed only to satisfy a dependency but are no longer needed.
