I know that some enterprise put this kind information in their engineering blog (for example the Linkedin: http://engineering.linkedin.com/ ). But What more exactly your are thinking to use?
Actually I'm still in the planning phase so was wanting to know if there are free or commercial ways to get "experts" to advise. I'm thinking of Cloudant for the database (particularly due to need for offline phone apps and bidirectional syncing), imgix for image serving (dynamic resize, etc), Wordpress for blogging, Bootstrap for the responsive framework, Mapbox for serving maps. Still totally undecided on things like Ruby on Rails, node.js, amber/ember/etc.js or bug tracking or usage/statistics tracking, phone developmpent platform (e.g. phonegap versus pure native), etc.
