I'd like to request that that design decision be overturned. Just because a post is viewed does not mean it contains useful information. It means that google thought it was important because of SEO reasons (not usefulness reasons). Or that the title was convincing enough to have people click on it (again, not measuring usefulness).
Unless Khoros has a "was this post useful to you" voting option, I don't see how it can measure the usefulness of a post. Since you can't measure the usefulness of a post, you can't sort by usefulness. Sorting by anything else does not accomplish the purpose.
Since the purpose can't be accomplished, you might as well save most of us the extra click switching over to the "most recent" sort option.
Now for general feedback: I'm not impressed with the new platform yet. So far, it's actually worse in one big way: I can't find the stuff that I'd like to take action on. There's no "unread" feed. The notifications bell is hit or miss sometimes loading a blank page. This is compounded by the fact that i have to log in multiple times a minute. The "most recent" sort option is the closest i can get to seeing the stuff i might be able to take action on, though the system does a poor job of highlighting which ones are unread by me (compounded by the login issue). Plus, there's no concept of "my feed" containing just those items/categories/forums/objects/whatever they're called that I've subscribed to. So, I end up going to the top level, sorting by "most recent" and trying to see what things I've responded to and what things I've not, mentally skipping over the marketing stuff that is syndicated over from the blog (which i never look at because it's too salesy).
These aren't uncommon pitfalls though. Facebook and Twitter/X also have this problem. They use an algorithm more complex than "most viewed", but the end result is the same: the stuff at the top of the feed isn't always everything and often is stuff i don't want.
