On the one hand, I like being able to quickly peruse the errata and see all the changes in one place.
On the other hand, I really liked their previous format for the errata, which included an explanation for changes and a reprinting of the full power/feat/etc so that you had no chance of misreading the errata.
I can't help but wonder if the change - and the minute amount of errata itself - is in some ways a response to the complaints about how many pages the errata document was. Or, alternatively, a result of them not having the time or resources to create a more extensive and complete errata update.
It could be possible that they just feel all the Essentials material is working perfectly and doesn't need any other errata, I suppose. And that DDI magazine content they can just fix within the articles themselves. I suppose I should listen to the optimist in me and hope that is the answer...
