I welcome MAG's acquisition of STN, and hope that it will bring improvements across the board for passengers, staff and airlines, local businesses and residents.
I'm a regular user of all the airports that purport to serve London (except Oxford 'London Oxford', and Lydd 'London Ashford'). However, it's not often that I'm actually going to London itself; I'm more often bound for various places in the Home Counties, and choose my airport accordingly.
I hope that the new owners of Stansted will recognise that the airport will benefit by becoming more of a multi-modal transport hub for towns to the north east of London; ease of access and connectivity across Essex, Hertfordshire, Cambridgeshire and Suffolk will be valuable in growing their market share.
