I just had an old question of mine closed by a moderator with the following comment:
I’m voting to close this question because it was asked a long time ago, and it is likely that an answer is no longer useful to the person who asked the question, or to the general bioinformatics community. Please feel free to edit the question and update it if you feel it's important to get an answer. – 7 hours ago
I then checked the mod's profile and saw that they've actually closed a total of nine questions with the same comment! I'm sure the mod means well, but this is a problem. First, a question's age is irrelevant, questions can be answered at any time and on SE sites we answer for the broader community not for the OP alone. So even if the OP has abandoned the question, that is no reason to assume that nobody else would benefit from an answer. So why would you want to forcibly bar a question from ever being answered?
Perhaps more importantly, there is no rule that says old questions should be closed, so I don't understand by what authority someone would presume to make this choice. Moderators have the ability to single-handedly close questions, but that should only be used for things that are blatantly off topic. Otherwise, it feels like the moderator is just imposing their own preferences and getting to choose what questions stay and what questions are closed. Again, I am sure the mod meant well, but this feels like crossing a very important line.
So, please reopen all of the questions you've closed just for being old. That is not how these sites work, you didn't come to meta to see if this is what the commnunity wants and, in my own opinion, closing such questions actively harms the site for no benefit whatsoever. The most important thing though is that closing such questions is imposing one person's choice on the rest of the community with no discussion or consultation. Please don't do this.
