What I'd really like to see from reddit is a much better way to cut to signal, eliminate noise, and foster real community and discussion. Improved authoring and moderation tools would also help.
I'm impressed by Reddit's scale, like some of its foundations, and use it myself for finding interesting links, some
good discussion, and as a blogging platform (see https://dredmorbius.reddit.com
). It's got a small (~700 subscribers) but useful following.
As a small subreddit, I see downvote brigades. I'd really
prefer discussions could stay live for more than 6 months (the topics I'm discussing could stay active for years), and that subscribers to the subreddit could opt to stay engaged in the discussions, most of which are typically single to double-digit in length -- this isn't multi-thousand-comment front-page stuff, nor would I want it to be.
RES's big editor is one of the best Markdown authoring environments I've seen, but I can't access it from mobile (Android). That should be stock Reddit. I'd very much like inline images to be a subreddit option (as a blogging platform they're highly useful). A data-takeout option (similar to Google's or Ello's). The Wiki is useful but without search, limited. Comments search would be really great as well -- Reddit's self post
search puts it head and shoulders above G+ as a repository of my own work.
Generally: the ability to filter in on specific items of interest, and comments of interest. High-rated comments buried in a deep thread are now lost, that's a negative.
And yeah, getting Reddit on stable financial footing would also be a Very Good Thing.
