It seems I missed the announcement at the beginning of the year but after a good 4 year run Dave and Aaron have said farewell to Instant Spot.
It was only recently mentioned on CFHour about having a blogging site like Wordpress done in CFML and I remember thinking about Instant Spot then. I still think done right there is space for it.
Do check out Daves obituary on the application and the trials and errors they went through during its life.
