To Webcast or to hold a local event?

I would like to know if developers are more likely to watch a webcast or attend a local event (assuming the topic is the same and it is of interest to them? Personally, I like the local events because there is more to be gained from the event than just technical information. The networking and other small talk can be very beneficial. On the other hand, it is nice to be able to sit back and watch a webcast in the convenience of my cube or reclining chair at home. What is more useful to you or which do you prefer?
