We ask questions here, we get replies and we still look for something better. It might be a good idea to raise a flag about worthwhile questions which have not satisfactory answers yet. There might sure be some maintainence work, but overall it will increase the value of this place and we all can benefit out of it. Flag raising can be requested and approved etc.. Listing such nodes and replies to them can help in flowing perl knowledge much deeper. It could be in the similar repsect that math evolved a lot, in search of proof for fermat's last theorem.
