Thread:Talk:How to contribute/3/4 less visits

What could have caused this drop after April 17 (same in all languages)? It may not be a bad thing given the over-exposure, but it's still curious.
 * Link is still there on top Wikipedias; not on mobile, but it never was AFAIK.
 * It shouldn't be a stats fault, other pages are constant.
 * Other ideas?
