Possibly too complex of a tool with not enough demand for it? It probably takes a certain type of individual (like us) to care about this sort of thing or to even think about it. Personally, I hate wasting time looking at 20 different things every time I want to get a complete picture of something. Imagine you had a dashboard where you could not only connect services, but add your own charts, documents, info, stickies, whatever.
Now that I think about it, I wonder how much could just be done with Zapier, google docs and some other services out there. Time to research!
