Topics I'd be interested in, concerning mostly things related to development and evaluation of PS:
- if people are content with the advisors in /help recently
- by which way people found PS (google, friends..)
- how many players are interested in RP /how many seriously RP / alternate between RP and PL / don't like to RP
- the age distribution of players
- from which countries players come from / what languages are spoken natively
- what OS'es (if linux what distro) are being used majorly
- if one isn't playing on his favorite OS, what OS would they like be able to play PS on?
- what features / area of features would be most liked to be implemented
- if people are content about GM decisions generally
- what sort of other games people play
- how many people would be interested in getting involved more deeply in development/forum moderation/ GMing if they had enough time and/or had the qualifications
Things I'd be interested in privately:
- to what music people listen to
- how many females/males are out there
- how many hours per day people play PS (max ever, average, now)
- how many people have family members playing as well
- how many people have met in RL after meeting in PS (and whether a relationship was the result ^^)
@ Alfonso:
Maybe you can make a short survey, concentrating on one aspect, let it run a week or two and do another survey concentrating on another aspect a bit after?
Some things (for instance the number of hours people play) is varying heavily over time, so you could ask those questions in each survey, giving a more detailed picture on those things.
It also would be interesting to see if the number of people participating in surveys is altering as well or stays constant.
And yes, concrete is the right word ^^
