When I started with UNA a week ago, as a new user I found it very irritating that you have different attachments under the add posts. You can't do a survey with one, but you can with blogs. I have not installed the photo module at all because I am using the album module. I think both together irritate people even more. The same is with the video module. You can upload videos in 5 places ... confusing ... do it like in TumblR;)

If you use almost all modules anyway then you have to build and structure the page very cleverly on your own, with the pre-installation alone you won't get far because otherwise it would be too confusing.
