Not the local feed, no. You can do so via web, but none of the apps are set up to do it afaik. Even via web, you'd have to be logged in somewhere to do more than view the feed, so it isn't really a useful thing since that process takes you out of the instance, or requires signing up on that instance

Lemmy isn't meant for that tbh. Maybe it'll be possible eventually, and maybe one of the apps or browser add-ons will figure out a way, I dunno.
