My limited numbers on the podcast at the moment are very likely because the performance sucks.
..or maybe people prefer Youtube...
There are 4 ways people can watch my videos:
However many different ways you choose to make content available, someone will use it. I'm sure if you offered to post out DVDs once a month a few people would use it.
The question is how many users of a particular distribution method would give up watching and not use another method , and is it worth the effort to support those people?
I know there will be a few people with quasi-religious objections to certain channels, but at some point you need to make a cost/effort vs. benefit choice.
I can see that it is important to offer some way to download for offline viewing, but it seems that there are ways to do this off Youtube, and presumably itunes isn't costing you anything for hosting. How many people would you lose if these were the only outlets?
Think about the possible tradeoff between user loss due to more limited distribution vs. gain due to you having more time to make more content.
I have no idea what the answer is, and our field is probably too specialist for mainstream stats to be meaningful (also most potential subscribers will be more tech-savvy than potential viewers of fluffykittens.com) , but one thing I do know is I've never had a single request from anyone to make my stuff available outside YouTube.
