Hi,
Speaking roughly, if I pay for 10 minutes of podcast content (1500 words) per month at 5 cents a word, that's USD75 a month. Each quarterly produced would have three pieces from other people, and my usual stuff. Their contributions would have a stronger Ars focus because I'm working on the Mythic Venice project and some paid RPG writing, and this cuts into my research time. If people paid a heap more, then I can have more length, or I can pay for art.
My podcast host, Libsyn, lowered their costs last year, so USD5 a month gets me 140 minutes of podcasting space, so I don't need more space to fit that extra in.
Pre 2023, USD5 was enough for 50 minutes a month, and the slight extra that the patreons gave me was spent to upgrade to a more expensive plan every so often, so I could put in longer episodes (basically any episode longer than 15 minutes was a result of this). Now that's not necessary I've been saving up that extra to pay for maps / deck plans for Mythic Venice.
Recently there was a jump in my number of Patreons (huzzah!) so currently the income is USD25 a month. That means my "extra" at the moment is USD20, which I can't effectively spend on extra recording time anymore. This has been going on for a while, so the "extra" bit has built up enough to pay for a couple of bits of Venice art or alternatively 4 of these 75USD pieces, hence the idea.
Most real magazines get around these problems by having people subscribe in advance. So, one of the fanzines says "Pay USD4.50 to get our magnificent stuff." I'd prefer not to have a cover price, because it takes me more (unpaid) time to deal with subscriptions, and because Ars Magica is such a niche game I don't want to paywall material for new players.
I'm happy to put in unpaid time and my incidental expenses for research (the biggest bit), equipment and power, but I'm not wanting to constantly pay large amounts to do this, hence the Patreon in the first place. Moving to paid contributors is a big step (although its easily reversible since I'm not using a subscription system).
