Sorry Christopher but we're focusing on brand new or "undiscovered" products that people don't already know. As much as people love Rdio, I think nearly everyone on Product Hunt knows or uses it already. Please don't hate me for hiding this. :)

I know, it's super subjective and I'm trying to find the right balance. Let me know if you have suggestions!

That's not a bad idea, Chris! Might be challenging when some people post the itunes URL vs. .com but maybe there's something there.

@rrhoover at first glance, looks like you could check the "tweet count" of the url when you accept it server side and make an assumption programatically if the tweet count is above a certain threshold for the product it is most likely "mainstream" and reject it or alert you personally to release it from a holding tank of sorts. E.g. I posted rdio and the product url has 22.9K tweets while digital ocean is around 118 tweets. It could be a quick first stab and automating the "balance" :)

@rrhoover Digital Ocean is today's #2 most upvoted product! CONFUSING. But I understand :)
