Snap.com is running a new service, Snap Preview Anywhere. It allows websites to have the links on their site show a preview of the linked site in a floating window. I have stumbled across several sites that are using this technology, and I find it distracting. I’m reading through a page, I scroll down and the mouse randomly ends up over a link. Poof! a pop-up window appears, and I’m looking at the preview of that linked page. It is quite distracting, partially because the preview is slow to load, and partially because something is happening on the web page that I’m not expecting. I’m not expecting anything because I’m not doing anything to cause something to happen. Simply moving my mouse and not clicking should not cause something to happen. The behavior is very similar to pop-up ads.
