The app seems to run fine right now, but I'll have to see how it goes. It is quite expensive though using Heroku but it is a lot easier to scale than using dedicated vitial machines like I did with MyColorscreen.com (my previous project).

For me personally, developing on rails made my life so much easier. There's a gem for everything. Facebook/Twitter/Foursquare can be integrated by just a few lines of codes.

Also in terms of resources like tutorials, rails community is by far the largest I've seen. Railscast.com really helped a lot in this project.

Do you mind sharing a bit more about cost? Heroku has a free tier; has the project already outgrown that?

Sure, I'm currently running on:

Heroku Postgres Crane: $50 (just in case) SSL Endpoint: $25 1 web dyno, 1 worker dyno: $34.50

I'm still using a free Sendgrid to send emails (200 emails per day) but I'm sure I'll have to pay more sooner or later.

I used to use DV provided by Media Temple and it only costs me $50/month.

It feels a bit slow now for me. Is it getting pummeled by HN?

By the way, cool project.

Did you mean Railscasts.com, with the extra s? Railscast.com does not look anything like so helpful!

Yes, you are right. Sorry about that, I was typing that on my phone. :)
