The user comments were mostly positive (1300 upvotes, 400 downvotes), and the site made a reasonable amount of money from the traffic, but the service was not compelling enough for people to use it daily. That's my fault, though, not Reddit's.
A "good" reddit submission is a bad article that makes the rest of your blog look iffy. 30k hits in a day, zero registration.
Seriously, if you want to make a good reddit submission, take an inflammatory/biased/extreme opinion pieces or research and quote the most provocative part of it as the title of your submission. Almost a whole paragraph.
How the heck does a "Full featured, open-source communication platform that includes e-mail, calendar, file management and contacts into a single page" get 474 referrals from Wikipedia?
You might want to focus on smaller bloggers since they're more desperate for content and more willing to write about you. Having multiple write ups from upcoming bloggers can can add up to more hits to your site.
It's more of an experiment though, since our traffic is already seeing a steady uptick.
