True. There are some exceptions like some former TIMGUL members. Most of that site was between 30 and 50 years old). On TI-Freakware there was Ranman too.
I think a generation of TI coder is about 3 years approximately. For example, in 2006, barely anyone who were around when I joined in 2003 were still active. By 2009, barely anyone I met in 2006 were active anymore either and if you compare the new Omnimaga forum with the old one, since 2010 began, barely anyone from the old board remain.
