A usual dilemma before starting a Rails project: Rails (Well known, well documented api, blogs, books) or Merb (Speed, Lean core, fresh framework, alternative ORMs). Today Rails and Merb core team
announced their decision to
merge into what would be known as Rails 3. Its a good thing since people would stop writing blogs about Rails vs Merb, and talk more about getting things done. I'm looking forward to a faster and less memory hogging version Rails.
