How are people going to be able to upvote their favorites with everything so disorganized? Group things by your products, sort suggestion posts by their kudos count, and when people add a new post, force that process through a search that reduces duplicates. Lastly, enable clear statuses that indicate whether a suggestion is being considered, implemented, or something else.
No offense, but it's 2016! Please see Microsoft's UserVoice sites or Spotify's suggestion forums as examples.
