What you're asking for makes sense. After all, if you share your gear photo to a place like reddit, you can have multi-threaded discussions. We think one of the benefits of posting gear setup photos on Equipboard is that won't get buried, unlike reddit or traditional forums. Furthermore you should be able to tag the gear in the photo, so that the photo then lives on the respective item's page.
(We're experimenting with that by the way - check out this photo with a "parts list", and this item with a new PHOTOS tab...)
So why am I telling you all this? Because before making comments on photos fancier, we need to get more Equipboard members aware and participating. Most Equipboard veterans don't remember what the website experience was like when they first joined. Well here's a hint - it kind of sucks!
We need to do a much better job of holding new members' hands a bit, and introducing them to the community features. After all, there are different types of Equipboard members. There are those that love to showcase their own gear and discuss it, those that only want to follow and contribute to pro artist pages, and those that are just database curators (adding/editing items, making sure they have the right specs, etc). And of course members that dip their toe in all that stuff!
But I know we definitely need to do a much better job onboarding new musicians and making them aware that every little contribution they do on Equipboard is making the entire thing better and better. And of course surface cool content in as many ways as possible so that it gets the upvotes/props/replies it deserves.
Currently new members that add great content can tend to feel like they're in an empty room - and it's on us, the Equipboard team, to fix that experience!
