I asked a question a few weeks ago that was closed. It reopened recently due to continous editing, but since it is no longer new, I can't seem to get responses from the community. Is there a hypothetical way to raise awareness about it?
Any edit or answer will show it as fresh again. This isn't like a common forum — posts are curated and older posts are still interesting. You don’t need “momentum” and “trendiness”.
In a fitting coincedence, I just got a gold “Great Answer” badge for a post made over a year ago (on a different SE). It was posted in January of last year, last edited in September.
Since your reputation is over 75, the right course of action is to set a bounty. With a bounty, you pay some amount of your rep (at least 50) to make your question both more visible and attractive.
Of course, a bounty can be seen as quite costly but if your question is good, you have all chances of getting it back from upvotes pretty soon.
Also, if you give us a link to your question here or on the chat, you have good chances of getting an answer that would bounce up your question on top of the active list.
