The typical font stacks IMO always forget to put "Liberation". For many Linux desktop users it's going to be the best available when Oxygen/Cantarell/Ubuntu aren't there. Many Debian users, for example, are going to have Liberation and not the others. It's sad that a fugly default is often going to be picked up for these users instead of Liberation. So: modern font stacks... Not bad, but not yet the panacea either (even for big websites who really should know better).
