I wrote this over the last couple of weeks using Rails 3, Twilio and a variety of Gems, putting in about 2 hours per day. I'd love any feedback from the HN community on any aspects of the site (design, API construction, documentation, marketing, pricing which is TBD).<p>On a related note: I have to say that I'm really flying with Rails 3. Typically I roll with Django, but have been super impressed with the Rails 3. Feels really clean, and there are some Gems that make the more mundane parts of the webapp construction fun and agile: Haml/Sass, blueprint, Fancy-buttons, Devise.<p>I'll probably write up a blog post soon on all the tricks & shortcuts I used to get this off the ground. Many of the shortcuts have to do with design and layout, and less so about backend coding.<p>http://phoneify.com<p>- @sghael
