I think we need no likes. This page is about photography. If you like a photo someone shares here, you can tell him/her that it's great. If you don't like it, you can tell what do you think to be wrong with it.
And what if a rumor of a camera or a lens gets many dislikes? Will Canon change the specifications? If so, I will give a dislike for all posts about STM and NanoUSM lenses until Canon decides to mark them as EF-V, and returns to ring type USM for all EF(-S) lenses.

Some time ago I've asked for a 300mm IS USM Macro that has a Minimal Focusing Distance about 1 meter. If this post gets many likes, will Canon release this lens sooner?
And if my beetle photos get many dislikes? :'( I surely won't stop taking them, just won't post them here.
