Some time ago when Technorati was all the rage Gareth Knight (aka oneafrikan) asked me if it is possible to build our own pinged server to aggregated content that we generate. Osiris was the end result. The first version was rough, it looked like a Google-esque design.
Osiris could use with a bit of a facelift — but time is an assert one never really has. In a short sweet summary of what Osiris is:
it keeps track of all updates across all the Growth projects — all of them.
I tend to refer to it is a robot that slaves away in the background just collecting data and organising it (it would make an interesting data mining exercise in the future). So far it has archived 18+ thousand updates since May, 2006.
