Hi Ian, Thanks for the response. What you wrote about partitioning the data etc. is exactly what concerns me with the Changeset Activity Publisher implementation - it will get too big with time.
On the other hand, for "social" purposes I guess there is no need to hold on to every single change since forever... Does anyone read Facebook posts from few months ago? Guess not... Slightly different use cases I think but still it would be good to learn from OWL devs knowledge about scaling something like this.
