I just scaled the heroku app to a hobby dyno :o,
This was a little play-around with ruby on rails, the twitter gem, I threw in a domain and twitter account and launched.
Next thing I know, I'm on Product Hunt (link), which is cool
Google analytics are saying I'm getting a ton of traffic, by my standards, on there, I went from around 600 votes to over a 1400
Good experience, hope the app ideas keep coming in and the voters keep voting
I'm guessing the next step will be to add some sort of better ranking algorithm, like HackerNews' one, or just have the ranking over a timescale.
