I think what would the OP is referring to is an "As it happened" type blog post, which would by necessity be separate from the GT.
These "As it happens" type pieces are done exceptionally well in the british press. Usually for sporting events, but also for any news.
These are basically a person posting about the event in real time in short 1-2 paragraph updates. Many of these are 'what's happening' but they also have recaps, share funny comments on twitter and people that email him during the course of events.
These are very popular and a great way to experience an event.
Here is an example from the Tour de France. You read from the bottom up:
