NIH is a willful decision to create something that already exists and is fully known to all interested parties, but summarily rejected on the basis that it is ... wait for it ... Not Invented Here. Sometimes, an identical result issues from identical circumstances wholly independently and honestly--leaving the world with nearly identical objects that attempt to solve an identical problem in an identical way.

Casually suggesting NIH can be an insult to the intellectual & creative abilities of a team. Sometimes it is warranted. Other times, it is not. I believe most guys and gals in the developer community are astute enough to ferret out NIH and ignore it.

P.S. On the other hand, you have a very impressive set of github repos. Kudos. You have successfully made me both care and jealous that I never get around to open-sourcing anything because I never feel like any side project is perfect enough to let others see (and because most of what I work on is closed-source for clients). Sad.
