Agreed.

This is what I was going to suggest, but I think we’d need to see what `ResponseBuilder` does to give you any actionable advice.

My gut feeling is that if I was in your shoes I’d replace `ResponseBuilder` with templates (e.g. jbuilder), and pass the results of the three fast (and simple) queries to the templates via the render call. I’m not sure what the forces are on `ResponseBuilder` (e.g. how often is it used, and what else might it interact with?) though, so I wouldn’t call it a solid suggestion just yet…

Could you share `ResponseBuilder` and `FeedBuilder` in a gist?
