This is pretty much how I have approached Curie recently. I got in just in time, with two approved submissions over the last two weeks.

It feels like "you know it when you see it." The post will look good, it's the right reputation and less than $1 payout, and it's within the 150 minutes - 24 hours time zone... and BOOM! You submit that to Curie, and it gets upvoted, and everybody wins.
