As a FORMER firefox developer (add-ons), I think my reasons for persona not taking off are as follows: 1. value proposition for developers was never clear 2. many saw it as a firefox only thing 3. chrome usage is overtaking firefox 4. I felt burned by developing for firefox in the past, why was I going to do it again (this is me personally, and is likely my #1 reason) 5. Never saw how it simplified my users lives. 6. I saw it as another waste of time like openID ended up being (and I loved the idea of openID, but so few people ever used it). /rant
