itch.io is fantastic for basically everything except the fact that the market is really small and fragmented, so you're almost always doing a lot of your own marketing and DriveThru does that better for indies, which is a little ironic.

With that said, DriveThru's cut is pretty big. It's more of a question of: Do I get a smaller fraction of a much larger flow, or do I go for a larger fraction of a lower flow? Itch.io makes PWYW a lot less obtrusive than DriveThru does, and DriveThru definitely has a better conversion rate for donations (in part perhaps because people like me always have some extra wallet credit from affiliate/publisher stuff).

For betas and stuff the reason I'm shying away from DriveThruRPG is that the interface to actually work with stuff on DriveThruRPG is a massive pain and I've found that it's very easy to mess up in ways that you don't want to mess stuff up. Almost all traffic on itch.io typically would be coming from outside, and that's not true for DriveThruRPG, but it is something that's almost 1:1.

I really do hope to do more freelancing. I've been enjoying it quite a bit. Portfolio work is nice; I've got a lot of writing under my belt but it's almost all self-published, and that doesn't look as cool as being able to say "I've written for X, Y, and Z."
