Mike Krieger (Instagram cofounder) wrote an article today on "Opbeat":http://blog.opbeat.com/2013/04/26/picking-tech-for-your-startup/ regarding the technology stack tech entrepreneurs should use for their startups. His advice could not ring more true to me (especially in light of my "previous post":/archives/2013/04/16/there-is-no-right-way-to-develop-software/).
bq. Ultimately, the most important thing to keep in mind is that your “stack” shouldn’t define you; while some engineers are attracted to companies working with cutting-edge tech, that shouldn’t be the driving force behind your early technology decisions. Instead, establishing a solid base with mature data storage, and augmenting more exciting recent projects where they can add value further up the stack will let your team stay focused on solving the challenges you’ve set out to solve.
In short, use the right tool for the job, even if it isn't sexy.
