It's a nice summary if you read the whole thing, but the alphabetical ordering (both by category and by title) is not great for a quick skim. If there is no 'priority ordering', the most important article is on average going to be buried somewhere in the middle.
It makes it easier for the Wikipedia editors (avoids endless arguments about priority), but not great for the average reader.
Along side each event it would be great to have a small link to a google news search for that event. Possibly even a google news search that isn't personalised or tailored to a location, if that's possible.
