Impressions with Heroku: Just Another Nice Toy for Deploying Simple Ruby on Rails Applications

I finally had a chance to play with Heroku cause I wanted to quickly try out OneBody - open source Ruby on Rails based social network.

I followed the instruction to create my app. What's missing there is that you'd need to generate public/private key before calling 'heroku create urapp'. It's as simple as issuing 'ssh-keygen -t rsa' for Linux. see GitHub docs for more information.

I also tried to use the import interface at Heroku to import OneBody, but it always timed out. Heroku should have provided a simple import command via Heroku gem to create a new application through importing.
