Sadly I've decided to give it a miss this year. I registered for my tickets early and was still dithering over my itinerary for the talks right up to last night - there are a lot of interesting speakers to choose between. However with an epidemic looking like it's descending on the UK (and especially London) it just didn't seem a sensible time to venture out to a large conference venue.
I've spoken with a former colleague who did decide to risk it, apparently the Excel centre was a bit of a ghost town, so it seems I'm not the only one.
