      No kidding. I use it pretty religiously, especially if I want to tail through it to get a real-time display of a certain class of errors. For instance, while specifically debugging PHP fatal errors I just do tail -f /var/log/apache2/error.log | grep "PHP Fatal" and I'll have a continuous stream of output where only fatal errors display.

      I'd be pretty lost without it, to be honest :)
