Who decides what goes into "gem install <gem_name>", and how do you decide which plug to use?
For example, delayed_jobthere is a version of tobi and a version of collectidea.
http://github.com/tobi/delayed_job
http://github.com/collectiveidea/delayed_job
Who decides what is included in gem install delayed_job? (Is everything official in rubygems.org?) And if we use something directly from GitHub, how do we decide which plug to use - for example, the version of tobi or collectidea?
