Great information - many thanks, @paulag !  As my posts are mostly in 'photography' (my chief interest here) - it's interesting to know the whales don't really focus on that (at a low 0.51%), but the rest do (top at 8.75%)!  So, I can add 'life' (5.6%) or 'steemit' (5.4%) to my tag list!  

Also of interest is that I have only seen two whales on my posts before (no wonder I'm slipping through cracks... lol) There's a whole lot of ocean of whales out there who don't see me... sighhh!  But I'm not the kind to go knock on their doors now; I'm more the kind to let Life's experiment take place - see if I get the others' attention naturally...  Upvoting and resteeming!
