I just wanted to chime in as someone who purchased Pot of Jam a few days ago. I consider myself a beginner, but since I've been in and out of it for 10 years and lurking in forums for most of that, I'm not a sucker for ad language. I've gotten pretty good at seeing through a demo/trailer and understanding the basic mechanics at work or at least their limitations. I watched the demo for Pot of Jam, and even though I'm not experienced enough to know exactly what's going on or be able to do it, I got the gist of it. I knew it wasn't all that original--though I'm not versed enough to know if it's been ripped out of some book. I basically knew that I could probably learn all the sleights necessary and figure it all out from Bobo/Greg Wilson/etc. But the hardest part about being a beginner is not knowing how to learn. There is a lot of material out there, and combing through it all, finding a routine that feels right for you, etc. can be discouraging.
I've long gotten over the phase where I have the urge to buy everything that Ellusionist/Theory 11/Dan & Dave release. For me now, these sites are useful curators. Sometimes it's nice to have someone package/repurpose a bunch of moves and put them together for a fun routine that's practical and good for someone without much experience. It's like buying beginner's workbooks for a musical instrument. It's all basic stuff that's pretty much repurposed from other places, but it's put together in a useful way for someone who is just starting out.
On the other hand, I can still agree that a lot of pretty pointless magic gets put out there by almost everyone. I will say I think Theory 11 is more selective than most about the effects they publish, and it shows. It's pretty easy to feel like some sites are just grabbing for easy cash from youngsters. At Theory 11 I always buy with confidence--though I still don't buy that often haha. I'm all about books these days. Has Theory 11 thought about becoming a distributor for some of the classics? That would be cool.
