It happens, really. Sit there day in and out and one day you look up and think: screw this.
I've been taking a bit of a break from Second Life, still in and out etc but haven't been seriously coding anything. That spark just isn't strong enough yet to inspire me to get back to it. I spent a large portion of the first year in SL scripting, I do enjoy it and don't plan to fully stop but everyone needs a vacation.
I'm still here, you can still comment or drop me an IM in world I just don't know what, or when, my next product will be coming.
*hugs*
