I've added SnapShopts from snap.com to my blog. This is a way to have an automatic preview of each and every external link on the site. It can be fine tuned, enabling or disabling specific links, so I might change how it works a little over time (suggestions are welcome). Since I like this feature from other sites, as I can figure out if I'm really interested in a link before opening it, I decided to add it to this blog and possibly to some of the other sites I manage (and there are quite a few) in the near future.
Notice, there is also a SnapShot plug in for Firefox. Interesting, although it makes it a little confusing to figure out on which sites it was originally enabled....
Later
As I got a few complains and noticed some weird links myself, I decided to keep the snapshot of the links only for the body of the blog posts, removing them from the rest of the site... but if I keep getting complains I'll get rid of them or let users activate them only if they like the idea.
