Seems to be a new thing on the cricinfo site (for the men's matches too). Really useful when you can't watch to be able to see all the big incidents just after they've happened.Loving the increased level of coverage that womens cricket is getting. Being able to watch the highlights online as it happens is great.
When I'm out I prefer following on cricinfo than watching on Sky Go (as it's easier to switch between emails, calls etc) and this combines the best of both.
