But what does it do?
It adds a function so that every hyperlink in a page can be a graphic preview to its destination. So when you mouse rollover a link, you can see, before you click, a small window version of that site, and it may convince you whether or not it is worth really following through with that click.
As a test, I “snapped” CogDogBlog today, so a previous post has a link to http://www.openaugment.org/. In the old web, you’d have to make some guesses based on the hyperlink’s text itself, the context in other content, and perhaps some guesses by seeing the URL in the browser status bar, to decided IF you really want to go there.
With snap, you also get a visual preview:
I’m playing with it to see if its worth keeping around and/or using elsewhere.
Obscure footnote: I vaguely remember that the snap.com URL was some front end for NMC — of which I found some relict proof in the Internet Archive. Did NBC drop the snap.com domain?
