Without DNSSEC, there is still a possibility of Kaminsky exploit. True, but misleading.
But to say 'most of the Internet remains vulnerable to the so-called “Kaminsky bug”' is less-than-responsible journalism. Patches have been available for years and all responsible sysadmins have deployed them. Success of a Kaminsky attack against a patched DNS server is possible but the chance is very, very low.
There are plenty of good reasons to use DNSSEC as there are quite a few vulnerabilities. But please don't put Kaminsky attack at the top of your list.
