I use Bing to search from time to time. It’s a decent alternative to Google, which I avoid entirely.
Overall, I appreciate Bing’s results but the everchanging page drives me insane. Things are constantly moving.
If I click a link and then press “back” to return to the Bing page, then Bing adds something underneath the link I just came from, which causes everything on the page to shift, causing me to lose my orientation on the page. Maybe it sounds petty, but it wrecks my flow.
