According to respondents Ruby is used as a development platform by 5.31%, well behind PHP's dominating 67.54% market penetration. However, when asked what platforms people were not currently developing for but planning to use in the next twelve months, Ruby was the answer of 24.37% of respondents!
Other results show 34.04% of developers are using unit testing and 17.78% are using MVC, both common methodologies used by Ruby on Rails.
