However in a post earlier today, Spolsky announced all four events have been axed including the one set to be held in Sydney, apologising profusely to those who'd signed up to attend the events and blaming himself for the outcome.
'I took a perfectly good thing (DevDays '09) and gold plated it until it was a different thing,' he wrote.
'This great 2.0 thinking had us building a really amazing conference series. We had great venues, great A/V, great food, insane Wi-fi, and of course, a schedule of two days of great speakers lined up in each city.'
Spolsky blamed poor attendance on the decision to axe the events, saying the changes made to this year's program including increasing the attendance price from $US99 to $US499 discouraged people from signing up.
'What we didn't have was an affordable, one-day, painless, no-brainer conference. So registration was surprisingly slow. And we just didn't get enough people to make it work.'
'Ooops,' he said, before confirming those who'd paid to attend the conference will receive a full refund automatically shortly.
As for future events? 'We want to work on a much larger number of much smaller events in far more cities, such as meet-ups and individual talks sponsored by Stack Overflow,' Spolsky said.
