I like (hah!) browsing through the recent snaps section through Glitch HQ (the Android app), but there is no option to "like" snaps or otherwise bookmark them for later perusal. In the web interface one can "like" a snap one likes and it will appear in a likeable list of liked snaps. One can leave comments on snaps via the HQ so it seems unlikely that this could not be implemented. It would certainly be useful!
