- Do you use Lisp:
   - at work (if so, how much) 
yes - a lot
   - for study (if so, how much)
   - as a hobby (if so, how much) 
sometimes
 
- Are you using Lisp as much as you would like to?
   If not, why not? 

no, other - non programming - things to do
 
- Do you see any obstacles to further Lisp growth (if so, what
   is the biggest obstacle in your opinion)?
 
1) Programming Languages courses in undergraduate education: trying to show how to do bad lisp 
programming in one week on some old machines in basement that nobody knows how to operate properly. 
Resulting CS student's perception of Lisp: slow and awkward.
 
2) lack of cheap uncrippled Lisp implementation ready for undergraduate exploration coupled with some 
interesting application API (e.g., game programming API). Very few student care about clever recursive 
list manipulation per se.
 
- Would you be interested in a Lisp-related job or contract work? 

possibly
 
- Is your organization interested in hiring Lisp programmers? 

sometimes
 
- Are you currently participating in Lisp-related meetings? 
yes
   If so, where and how often? 
once a month
   If not, would you be interested in such meetings?
