While this would be too far-fetched call for me to count self as a "developer", I can say that my reasons started more with curiousity (philg, aD, wtr, PANDA, and Tcl/SQL for Web Nerds), then the appreciation that I was getting quite a few things done quick and with very acceptible quality (much faster than in the LAMP (or LAPgP) case, since I was reusing a lot of ready-made code). After that, there came a "code-base" and "lock-in" state -- I know have no compelling reasons to switch to any other platform.
No, as said, I can't really count myself as a real developer -- but I like to tinker a lot with the toolkit. Still -- the €0.02, FWIW.
