I was quite bemused by the backlash which erupted over a month ago about the Snap Previews. As I have described elsewhere, I actually liked the Snap previews, but I felt that I had no choice but to turn them off, such was the vehemence of the reaction against them.
Snap has responded to its critics in a few different ways. The most important way is that they have allowed the previews to be opt-in. On that basis, I have brought them back. You only see them if you choose to turn them on. If you do turn them on, you'll see that I've taken a minimalist approach to configuring the previews. The preview bubble only shows if you hover over the little icon. Hovering over just the link is not enough to trigger it. If you like, you can turn on the previews, refresh the page and see how they work, and then turn them off again by clicking in this box and then refreshing the page. Then they're gone, I promise.
