FYI, all: Please know that I am aware that commenting on photos on the site is currently more difficult than it was before, and that I am actively working with Hoop.la to try to get the following two issues addressed:
- Not able to comment on clips at the clip thumbnail level (without opening the clip)
- Not able to easily return to jumping-off point on the clip thumbnail page (i.e., once you open and comment on a clip, if you hit the back bar on your browser or backtrack through the site's breadcrumb trail, you get bounced to the top of the clips page rather than back to the photo where you left off)
Since commenting and interacting on the site are so vital to this community, these two items are currently at the top of the list of site issues that I am addressing right now.
But, please be aware that, unless the issue is a bug (something not intentionally programmed by Hoop.la) or a substantial number of their communities also share the same concern, I have to pay, usually considerable amounts, to restore functionality. The latter isn't a possibility, so I am just waiting now to see how they respond to my trouble reports.
**** WORKAROUND ON THIS ISSUE ****
In the meantime, there is a workaround that will reduce the amount of scrolling needed to comment on photos.
You can hover over the image you want to open, and issue a Command-click (Mac) or a Ctrl-click (PC) to open it in a new tab without closing the site. So when you're done commenting on the photo in the new tab, you can just return to the old tab and pick up viewing photos where you left off.
Please note that, depending on your browser, these commands may be different. For instance, in Chrome, I can also right-click on the photo and select "open link in new tab" and get the same result.
Again, I'll let you know of any new developments as soon as I know, but, rest assured, I am working on this! Please be patient and carry on, commenting as best you can! 
P.S. The good news is that this backtracking issue does not exist in the blog or forums areas. In both of these places, if you click on your browser back arrow, you should be returned to your jumping off point. But if you click on the previous item in the breadcrumb trail, you will be returned to the top of whatever section or page you were previously on. This setup is ideal, because it allows you two options for backtracking - both of which you might need or want from time to time.
