That's the saddest part of all. DC seem to enjoy 'rebooting' titles and wiping out history at the drop of a hat - they think it will encourage people to read the title. At the end of the day does it matter that the title may have a long sprawling history? If the writers are good then they shouldn't have to rely too heavily on the past, like when Grant Morrison wrote New X-Men for instance.
At the end of the day this sort of reboot ends up frustrating many readers and in a sense rubbishing/degrading what previous writers have done with the title.
