Weaponry
We are working exclucsively on macs, using TextMate for development, Balsamiq mockups / Inkscape / Skitch for graphics stuff.
Besides Rails (the obvious choice for bigger web-apps) we really like Sinatra too. We prefer haml/sass, jQuery, RSpec+Cucumber+Webrat, Datamapper / ActiveRecord on and off Rails. Passenger for deployment, git for source control (our code lives at github.com), though I guess that's just stating the obvious. Hosting our stuff on brightbox (heavier Rails apps) and dreamhost (everything else).
We are not scared of Javascript either - we heavily prefer jQuery, and we are OK with pure, hand-sliced Javascript/DOM scripting as well. We have quite some experience developing Firefox extensions too.
Last but not least, we think Ruby is the best thing since sliced bread - pure Ruby development is one of our core strengths as well.
