I think that the most important section feels like the “community” one, there’s lots of potential for a big expansion there. People react well to the idea of community, and the shared (or in this case various) experiences with a common project bring people closer together – so, discussions or user tutorials or just pictures of how yours and other people’s are going.
For someone who hasn’t heard of the Biopod before, I think it is probably important to make the main page a little more clear – action plans, mission statement, descriptions of what it’s all about, maybe something interactive (like a map which shows the locations of biopods around the world – obviously if this wasn’t a fake website!), things like that bring someone on the outside into the experience, again, forming an interest and a connection which could be good for gaining a wider audience/usership.
Like I said in the first answer, I think it’s a mixture of the two. Because you can rally feedback between users and that sense of ownership/belonging etc is a really key part of making something work.
I like the idea of a photo diary type thing, so that people can be positive about what’s going on with your system and offer constructive feedback etc. Graphs don’t really mean a lot to me
