Ive been giving thumbs up and acorn(s) to everything with a pollinator in it. Not just for that but always the those. I had no idea that this would sway the thumbnail chosen to represent that plant. If someone takes the time to give me a thumbs up or acorn(s) I have a look through their photos etc. The thumbs up also sways the ranking of the common name I think. The number of photos will at some point be a detractor but ATP is nowhere near that. I plan to replace some of my own when the right replacement comes along. I do like to see all the seasons and all the parts and the whole. The macros are a must for some features. I will, from now on, be more judicious with my thumbs up now that i no there more than just a compliment.
