Yeah, it's good to know that you are at least keeping up with the exciting ideas. Better than being completely surprised by it. It's also nice to get some perspective on how other people think about the topic.
Better than creating something that nobody wants or cares about certainly :)
Also, don't let this stop you. If you really feel like giving up though, consider open sourcing it, I suspect some people (myself included) are interested in this, but hesitant to give our info away to some untrusted 3rd party.
I'm not giving up. There are a few things they totally missed here like the fact I have to give away all my data and that it's not platform based (I can't build on it). I would like to be able to ad-hoc query and visualize my social data on my own terms locally. Not much written yet, but I will probably be open source.
