In creating UMB.FYI we have automated the aggregation of a lot of Umbraco data points, pulling this data into one succinct stream (well, two actually, one for news and one for events). We did this mostly to make things easier on ourselves when putting our newsletters together. However, whilst doing so we realized that this could be really useful for other Umbraco media creators who also report on Umbraco news.
To save everyone reinventing the wheel, we have decided to expose our unfiltered/unprocessed RSS streams for others to use.
NB We don't currently have any kind of rate limiting on these feeds so we will monitor their usage. If we find they are getting abused, we reserve the right to take them offline until a solution is found.
