There's also lnav (http://lnav.org), the Logfile Navigator. It can do what 'tail -f' and 'less' do plus: syntax coloring, filtering, loading compressed files, interleaves log messages from multiple files, and more.

Many of the comments I see on here about using '-F' with tail instead of '-f', live searching, and so on are handled in lnav by default. I would really encourage folks to give it a try.
