I saw this question on main site. This question has bumped to the homepage by Community. Description is given as This question has answers that may be good or bad; the system has marked it active so that they can be reviewed., that I understand.
My question is what is mean by "bumped to the homepage"? What is the homepage referring here? When do we do this and who can do this?
Now when I am looking at the above question there is no 'bumped to the homepage' mark. How did it get removed?
Every hour, the Community user finds a question with at least one answer, but none of the answers have a score greater than 0, and there's been no activity for 30 days or more. To gain exposure, it "bumps" them to the homepage, i.e., the main page of Web Apps, by making a silent edit. (Why it's called "bumping", I don't know. I prefer the similar "nudging", but "bumping" is what gained a foothold in most discussion forums and related sites.)
This activity isn't new; this has been happening for a long time. They've only recently added the text to let you know it's been "bumped". This distinguishes it from other actions which kind of look the same, like a spam answer being auto-deleted. I expect this is to encourage the reader to give the answers a good review and vote accordingly.
As for why the message isn't there any more, I'm sure it's because someone edited a post (either the question or an answer), so that's the reason that the question is appearing high in the list of questions on the home page. (The "bump" message ages away after three days, but it doesn't look that that's what happened here.)
