I like that it is easy to use, has many features but also allows for customizations as needed by your organization's needs/requirements (and you can even do this via their API). It does not integrate with Slack or other messaging platforms very well at all which seems odd considering how much of an emphasis they place upon integration in general. If there are no integrations available then maybe consider another option? We have been using backFeed since we started our new project about 2 years ago now so haven't had any issues yet! The only thing i dislike right off hand would be if someone could give me some examples / links where people did implement slack into backefedding because currently none exist - however from what ive read others might know more than myself here :D.
