I try to scan the unanswered posts as much as possible for a couple of reasons.
#1, No post should go unanswered, even if you are just bumping an issue that has been unanswered, if you can't answer it, at least by bumping the issue and subscribing you will hopefully get the right answer from someone else who can share this knowledge with you.
#2, New users have heard of the amazing forum response and to make their first post, or one of their firsts and have it go unanswered is a bit discouraging.
I myself sometimes forget about the "unanswered posts" button and get caught up in adding to repetitive answers in topics of "I'm thinking of switching to Ubuntu." Plenty of other people will and always have answered that question for users. We should really try to solve as many issues as we can and be as diverse as we can.
I missed the last meeting and will hopefully be at the one on the 12th, maybe we can bring up this issue, if it is an issue, at the next meeting.
