I have been using Stack Overflow for a couple weeks now as an active member and have previously been aware of the site through searching Google for answers to questions.
I have found that most of the questions I have asked have been promptly and thoroughly answered by an experienced userbase, but I have several questions which I see slipping into the abyss unanswered whcih I suspect may never be due to their decreasing level of visibility.
As a new user I have no hope of raising a bounty on any of these questions to solicit a response. I also dont see my reputation going up particularly quickly because any question I would have a chance of answering is picked up within seconds and answered better than I ever could by someone with greater knowledge.
This means the only way I can see of raising my reputation high enough to bring attention to these questions any time soon would be to spam the system with easy to answer questions (don't worry, I won't).
Therefore what I would like to see is some way for users with low reputations to be able to offer a bounty or at least in some way encourage an answer to a question - for example allowing them a free 50 rep bounty once a month to offer on an important question that has not been answered for a period of time and has not been downvoted (is a sensible question that is not easy to answer.)
We are probably the ones who need the most help after all.
P.S. love the site - I've leart more in the last two weeks of membership than the two months previous.
