Great! Lots of people on Hacker News use AWS because places like Linode and DO don't actually have all the services and scale their work requires. Believe me, we agree that this announcement is several years overdue. I think most engineers who work in AWS would also agree. But when you get to their scale, it's hard to make big changes like this in a safe way. The fact that it rolled out in a brand-new region (us-east-2 only for now) is good evidence that they are being very very careful with this rollout.
And as mentioned, the reason there are so many AWS posts this week is because they save up all their announcements for the conference going on right now. I sorta wish they'd spread the stuff out more, myself, but these are mostly HN-front-page quality announcements. It's just a year's worth of work dumped all in two days.
