Can we at least be clear about the fact that 99% of what came out for 4e was not errata at all, but rules updates? Very little of 4e actually needed errata. I'd say on a proofreading level, it was miles ahead of most other games, including other versions of D&D. But a game that focused on balance was bound to need tinkering...not to fix errors but to keep things balanced, or update classes. I personally liked the engagement the dev team had keeping 4e feeling fresh.
