One of the more popular suggestions from We're not a Q&A site. But what should be done about it? was to change the search bar's placeholder text. We've been asked to flesh this out in a separate feature request so that SE can look into whether they'll make these changes for us.
So you don't have to follow the link above, here is the proposal:
Modify the placeholder search bar text
If you look at the top right corner of the page, you'll see a search box with the placeholder text "Search Q&A." Even outside of the context of deemphasizing the Q&A terminology on our site, I think this could be better phrased as "Search the site" or similar. So while we're requesting that Q&A-specific text be changed, we might as well request this as well.
So this post is here to discuss the proper wording for that placeholder.
