For DjangoCon Europe 2014 we have decided to follow the traditional DjangoCon scheme, according to which speakers pay for their tickets just like all the other attendees.
We've taken this decision for a number of reasons.
Chiefly, doing this allows us to lower the price of all tickets, making the event more affordable to all within our budget.
Also, we'd like to have more talks than ever before at a DjangoCon Europe - 30 or 40, or even 50 - by having more slots for shorter talks of different lengths. It would not be feasible to offer free tickets to all these speakers, and it would be invidious to offer free tickets only to some.
All the same, we do realise that some potential speakers may find the cost of attending the event an obstacle. So: if you'd like to do a talk and your proposal is accepted, but you'd find it difficult to meet the costs, please get in touch with us, because we hope to be able to offer support to speakers in that situation.
