I can't believe you managed to get this submitted to HN before I did. That's what I get for posting it to twitter before coming here ;D Since I knew the URL, I could have totally cheated and done it before even uploading the blog post.
Joke aside, thanks for the great new release. I'm running 0.6 in production sometimes with 3000+ connected users and will soon need to scale. Being able to do so just by upgrading to 0.8 will make my life easier... until many more users come, of course.
I posted the above comment to say I was really happy and all (and I wasn't trying to be an ass) - I wish people would stop upvoting that stupid, non-constructive comment (for some reason, it has 10 upvotes).
