Practical me: Having that information allows better decisions to be made. Rather than simply wasting my evening at a station other arrangements can be made, possibly having a meal in a local bar/restaurant rather than shivering on a station.
Saying all this though, the level of service is low when compared to other countries' commuter rail systems. One of the challenges VRE works with is that it hasn't owned the rail lines it's running on; they're owned by a freight railroad and passenger rail is typically run at a lower priority than freight. There has been some recent movement though by the state [5] to significantly improve passenger rail transit, especially in the northern part of the state (almost certainly related to Amazon HQ2).

This kind of jingoistic comment demonstrates how a tactical post with some technical information, can massively skew judgement. According to Network Rail, the routes in question are not only one of the most congested in the country, but have been mired with problems of under-investment and lack of desire to ease the bottleneck. Some of the routes connect salubrious stock-broker belts with the City of London, in addition to Brighton & Hove, East Sussex. Other routes traversing East Croydon, acting as a hub, also serve the mainline stations of London Victoria and London Bridge to (London) Gatwick ─ the second busiest airport in the country.
I wonder how many people will be forgiving or cheering for Network Rail and handing out accolades for their neatly constructed blogs, when they miss their flight or arrive to work late 'due to signalling problems'.
