First, the fact that these buildings replace trade as the main means of increasing relationships between races means that Matter Compression and Matter Transmission techs are absolutely vital.
Second, there's the fact that there are like twelve different buildings, which produce vibes for four different races. The complexity is really hard to grasp. "So I want to make race X like me...What are my options? Who's going to get mad?"
Third, you will want to build the buildings that a race objects to on their world. E.g. have Andors build Hologram Channel: Reality, so the -0.30 penalty is irrelevant. Building in this style gives you an advantage, but also restricts the federations that can form. It also seems wrong for role-playing reasons.
Attached is my idea for computer advisor screen to summarize the races. It would be nice to have the race icon clickable, which would filter out only the buildings that affect the attitude of that race.
I added your figure to the wiki here, even though it is slightly out of date (i noted that it changed in 1.012):

If someone wants to update the figure, feel free.
What do the +30 and such numbers actually mean? Should it be +.30 per month?
