Every once in a while, someone finds an old post via an internet search. They then post "I have this problem too," which resurrects the old post. For example, this post from 2012 was recently resurrected.
IMHO, the old posts should hang around, but should be set to read-only after a certain period of time, such as 6 months or 1 year. That forces new OPs to open a new question. I think this is a good idea because the new OP has different data and is running a different version of SAS from the original OP. Also, the new OP often has a slightly different question than the original OP.
I have seen old posts set to read-only in some other Q&A forums, so there is a precedent for this action.
Please discuss.
